Elapsed Time (Intro) — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. An analog clock shows the hour hand on 3 and minute hand on 12. Digital time is 3:00.
When the minute hand points to 12, the time is exactly 3 o'clock.
2. Digital time 6:30 shows on an analog clock with the minute hand on 6.
30 minutes past the hour is halfway around, which is the 6 on the clock face.
3. An analog clock shows 2:15. One hour later, the digital clock reads 3:15.
2:15 plus 1 hour moves the hour number up to 3:15.
4. An analog clock shows 4:45. Thirty minutes later, the digital time is 5:15.
4:45 plus 30 minutes crosses the hour, landing on 5:15.
5. Digital time 9:00 plus 45 minutes later on an analog clock has minute hand on 9.
Each number marks 5 minutes; 45 minutes lands on the 9.
6. An analog clock reads 10:30. Digital form is 10:30.
Hour hand between 10 and 11 with minute hand on 6 means 10:30.
7. Digital 7:15 to digital 7:45 is an elapsed time of 30 minutes.
45 minus 15 is 30 minutes.
8. Analog 1:00 to analog 2:30 is elapsed time of 1 hour 30 minutes.
From 1:00 to 2:00 is 1 hour; 2:00 to 2:30 adds 30 minutes.
9. Digital 11:45 plus 15 minutes is 12:00.
11:45 plus 15 minutes crosses to 12:00.
Part B: Matching

1. Match each item to its correct answer.
Analog: hour hand on 8, minute hand on 12
→ Digital 8:00
Digital 8:00
Analog: hour hand past 4, minute hand on 3
→ Digital 4:15
Digital 4:15
Digital 6:30 plus 1 hour
→ Digital 7:30
Digital 7:30
Digital 2:00 plus 15 minutes
→ Digital 2:15
