Tell Time Minutes · Grade 3 · Worksheet 1

1. What time is shown when the hour hand is between 9 and 10 and the minute hand points to 37 minutes? Answer: 9:37 Solution: The hour hand is between 9 and 10, so the hour is 9. The minute hand points to the 37th minute mark. On an analog clock, each small mark is one minute.
   Full step-by-step solution

   Step 1: The hour hand is between 9 and 10, so the hour is 9. Step 2: The minute hand points to the 37th minute mark. On an analog clock, each small mark is one minute. Starting at 12 (which is 0 minutes), count 37 marks clockwise. Step 3: Combine the hour and minutes: 9:37. Final answer: 9:37.

2. What time is shown when the hour hand is between 3 and 4 and the minute hand points to the 7? Answer: 3:35 Solution: The hour hand is between 3 and 4, so the hour is 3. The minute hand points to the 7. Each number on the clock represents 5 minutes.
   Full step-by-step solution

   Step 1: The hour hand is between 3 and 4, so the hour is 3. Step 2: The minute hand points to the 7. Each number on the clock represents 5 minutes. Count by fives from 12: 12 (0), 1 (5), 2 (10), 3 (15), 4 (20), 5 (25), 6 (30), 7 (35). So the minutes are 35. Step 3: Combine the hour and minutes: 3:35. Final answer: 3:35

3. A rectangular playground is drawn on a grid. The longer side measures 150 feet and the shorter side measures 90 feet. What is the perimeter of the playground? Answer: 480 feet Solution: Identify the lengths of all four sides of the rectangle. The longer side is 150 feet, and there are two of these: 150 + 150 = 300 feet. The shorter side is 90 feet, and there are two of these: 90 + 90 = 180 feet.
   Full step-by-step solution

   Step 1: Identify the lengths of all four sides of the rectangle. The longer side is 150 feet, and there are two of these: 150 + 150 = 300 feet. The shorter side is 90 feet, and there are two of these: 90 + 90 = 180 feet. Step 2: Add all four sides together to find the perimeter. 300 feet + 180 feet = 480 feet. The perimeter of the playground is 480 feet.

4. Emma's family is driving to visit her grandparents. They left home at 9:15 AM and arrived at 11:38 AM. To the nearest minute, how long was their car ride? Answer: 143 minutes Solution: Calculate the time from 9:15 AM to 11:15 AM From 9:15 to 11:15 is exactly 2 hours 2 hours = 2 × 60 = 120 minutes Calculate the additional time from 11:15 AM to 11:38 AM From 11:15 to 11:38 is 23 minutes 120 minutes + 23 minutes = 143 minutes 143 minutes is already an exact number of minutes, so…
   Full step-by-step solution

   Step 1: Calculate the time from 9:15 AM to 11:15 AM From 9:15 to 11:15 is exactly 2 hours 2 hours = 2 × 60 = 120 minutes Step 2: Calculate the additional time from 11:15 AM to 11:38 AM From 11:15 to 11:38 is 23 minutes Step 3: Add the two time periods together 120 minutes + 23 minutes = 143 minutes Step 4: Check if rounding to the nearest minute is needed 143 minutes is already an exact number of minutes, so no rounding is needed The car ride took 143 minutes.

5. Aroha's clock shows the hour hand just past the 9 and the minute hand pointing at the 32. What time is it? Answer: 9:32 Solution: The hour hand is just past the 9, so the hour is 9. The minute hand points at the 32. On a clock, each number represents 5 minutes, but the minute hand can point to any minute mark.
   Full step-by-step solution

   Step 1: The hour hand is just past the 9, so the hour is 9. Step 2: The minute hand points at the 32. On a clock, each number represents 5 minutes, but the minute hand can point to any minute mark. Here it points directly at the 32nd minute mark. Step 3: Combine the hour and minutes: 9:32. Final answer: 9:32

6. Noah looked at the clock in his classroom and saw that it was 11:46 AM. He realized his favorite show starts in 21 minutes. What time will his show start? Answer: 12:07 PM Solution: The current time is 11:46 AM. We need to add 21 minutes. Step 2: 46 minutes + 21 minutes = 67 minutes.
   Full step-by-step solution

   Step 1: The current time is 11:46 AM. We need to add 21 minutes. Step 2: 46 minutes + 21 minutes = 67 minutes. Step 3: Since there are only 60 minutes in an hour, 67 minutes is 1 hour and 7 minutes. Step 4: Adding 1 hour to 11:46 AM gives 12:46 PM, but we only add the extra 7 minutes, so the time is 12:07 PM. The show starts at 12:07 PM.

7. Lily's music lesson starts at 3:45 PM and lasts for 35 minutes. What time does her lesson end? Write your answer in the format 'hour:minute AM/PM'. Answer: 4:20 PM Solution: Start time is 3:45 PM. The lesson lasts 35 minutes. Add the minutes first.
   Full step-by-step solution

   Step 1: Start time is 3:45 PM. The lesson lasts 35 minutes. Step 2: Add the minutes first. 45 minutes + 35 minutes = 80 minutes. Step 3: Convert the total minutes into hours and minutes. Since 60 minutes = 1 hour, 80 minutes = 1 hour and 20 minutes (because 80 - 60 = 20). Step 4: Add the 1 hour to the start time. 3:45 PM + 1 hour = 4:45 PM. But wait, we added the full 80 minutes as 1 hour and 20 minutes all at once. Let's break it down more carefully to avoid confusion. Better Step 2: Add minutes to the start time's minutes. Start time: 3:45 Add 35 minutes: 45 + 35 = 80 minutes. Step 3: Since 80 minutes is more than 60, we convert 60 minutes into 1 hour. 80 minutes = 1 hour + 20 minutes. Step 4: Add the 1 hour to the hour part (3), so 3 + 1 = 4. The remaining minutes are 20. Step 5: Combine the new hour and minutes. Hour: 4, Minutes: 20. The time of day period (AM/PM) does not change when crossing from 3 PM to 4 PM. Step 6: Final time is 4:20 PM. Answer: 4:20 PM

8. A rectangular classroom floor is covered with square tiles. There are 24 tiles in each row and 15 rows of tiles. How many tiles are on the entire classroom floor? Answer: 360 Solution: There are 24 tiles in each row There are 15 rows of tiles To find the total number of tiles, multiply the number of tiles per row by the number of rows 24 × 15 = 360 The total number of tiles is 360.
   Full step-by-step solution

   Step 1: There are 24 tiles in each row Step 2: There are 15 rows of tiles Step 3: To find the total number of tiles, multiply the number of tiles per row by the number of rows Step 4: 24 × 15 = 360 Step 5: The total number of tiles is 360.

9. A rectangular playground is drawn on a grid. The longer side measures 150 feet and the shorter side measures 80 feet. What is the perimeter of the playground in feet? Answer: 460 Solution: Identify the lengths of all four sides of the rectangle. The longer side is 150 feet, so there are two sides that are 150 feet each. The shorter side is 80 feet, so there are two sides that are 80 feet each.
   Full step-by-step solution

   Step 1: Identify the lengths of all four sides of the rectangle. The longer side is 150 feet, so there are two sides that are 150 feet each. The shorter side is 80 feet, so there are two sides that are 80 feet each. Step 2: Add all four sides together to find the perimeter. Perimeter = 150 + 80 + 150 + 80 Step 3: Calculate the sum. First, add 150 + 80 = 230 Then, add 150 + 80 = 230 Finally, add 230 + 230 = 460 Step 4: State the final answer. The perimeter of the playground is 460 feet.
