Time to the Minute — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. If a movie starts at 3:25 and lasts 30 minutes, it ends at 3:55.
Starting at 3:25 and adding 30 minutes makes 25 + 30 = 55, so the movie ends at 3:55. The hour stays at 3 because 55 is less than 60.
2. The minute hand on 7 means 35 minutes past the hour.
Each clock number is worth 5 minutes, so the 7 stands for 7 × 5 = 35 minutes past the hour.
3. From 11:15 to 11:45, 30 minutes have passed.
From 11:15 to 11:45, the hour doesn't change, and the minutes climb from 15 to 45. Subtracting gives 45 - 15 = 30 minutes.
4. If you start homework at 4:50 and finish at 5:10, you worked for 20 minutes.
From 4:50 to 5:00 is 10 minutes, then 5:00 to 5:10 is another 10 minutes, for a total of 20 minutes of homework.
5. The hour hand between 9 and 10 with the minute hand on 4 reads 9:20.
The 4 on the clock means 4 × 5 = 20 minutes past the hour. Since the hour hand sits between 9 and 10, the hour is 9, giving 9:20.
6. From 6:00 AM to 6:45 AM, 45 minutes have passed.
From 6:00 AM to 6:45 AM, only the minutes change, going from 0 to 45. So 45 minutes have passed.
7. If soccer practice starts at 3:30 PM and lasts 45 minutes, it ends at 4:15 PM.
Starting at 3:30 PM and adding 45 minutes gives 30 + 45 = 75 minutes, which is one hour and 15 minutes past 3, so practice ends at 4:15 PM.
8. A clock with the minute hand on 10 shows 50 minutes past the hour.
Each clock number stands for 5 minutes, so the 10 marks 10 × 5 = 50 minutes past the hour.
9. From 8:20 to 9:00, 40 minutes have passed.
From 8:20 to 9:00 is 40 minutes, because it takes 40 minutes for the clock to climb from 20 up to 60, which is the next hour.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Minute hand on 2
→ 10 minutes
40 minutes
Minute hand on 4
→ 20 minutes
55 minutes
Minute hand on 8
→ 40 minutes
10 minutes
Minute hand on 11
→ 55 minutes
20 minutes
Multiplying each clock number by 5 gives its minute value: 2 × 5 = 10 minutes, 4 × 5 = 20 minutes, 8 × 5 = 40 minutes, and 11 × 5 = 55 minutes.
