Time to the Minute — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Emma started reading at 4:35 PM and read for 25 minutes. What time did she stop?
A) 4:50 PM
B) 4:55 PM
C) 5:00 PM
D) 5:05 PM
Starting at 4:35 PM and adding 25 minutes lands on 5:00 PM. From 4:35 to 5:00 is 25 minutes, since 35 + 25 = 60, which advances the clock to the next hour.
2. A bus leaves at 7:48 AM and arrives at 8:23 AM. How long was the ride?
A) 25 minutes
B) 35 minutes
C) 45 minutes
D) 15 minutes
From 7:48 AM to 8:48 AM would be a full hour, but the bus arrives at 8:23 AM, which is 25 minutes before 8:48. So the ride is 60 - 25 = 35 minutes. You can also count: 12 minutes from 7:48 to 8:00, plus 23 more minutes to 8:23, equals 35 minutes.
3. Which clock shows 10:42?
A) Hour hand past 10, minute hand between 8 and 9
B) Hour hand on 10, minute hand on 8
C) Hour hand past 10, minute hand on 6
D) Hour hand on 11, minute hand on 8
At 10:42, the hour hand has moved past the 10 because 42 minutes have passed in that hour. The minute hand sits between the 8 and 9, since 8 marks 40 minutes and 9 marks 45 minutes, and 42 falls between them.
4. Jake left home at 3:15 PM and walked for 18 minutes. What time did he arrive?
A) 3:28 PM
B) 3:33 PM
C) 3:38 PM
D) 3:43 PM
Adding 18 minutes to 3:15 gives 3:33, because 15 + 18 = 33. The hour stays the same since the total minutes don't reach 60.
Part B: Fill in the Blank
Write the correct answer on each line.
1. If lunch starts at 11:50 AM and lasts 35 minutes, it ends at 12:25 PM.
From 11:50 AM to 12:00 PM is 10 minutes, leaving 25 more minutes of the 35-minute lunch. So lunch ends at 12:25 PM.
2. From 9:37 to 10:07, 30 minutes have passed.
From 9:37 to 10:00 is 23 minutes, then 10:00 to 10:07 adds 7 more, giving 23 + 7 = 30 minutes total.
3. A class starts at 1:22 PM and ends at 2:07 PM. The class lasts 45 minutes.
From 1:22 to 2:00 is 38 minutes, and 2:00 to 2:07 is 7 more, so the class lasts 38 + 7 = 45 minutes.
4. If it is 6:53 PM now and dinner was 28 minutes ago, dinner started at 6:25 PM.
Counting back 28 minutes from 6:53, you can subtract 28 from 53 directly: 53 - 28 = 25, so dinner started at 6:25 PM.
5. From 3:18 to 3:46, 28 minutes have passed.
Both times share the hour 3, so just subtract the minutes: 46 - 18 = 28 minutes have passed.
