Question

Estimate each elapsed time to the nearest hour

Answer 1

1. 1:38 AM to 4:38 AM is 3 hours, 4:38 AM to 4:50 AM is 12 mins. This means that total time elapsed is 3 hours and 12 mins. Rounding to nearest hour gives 3 hours.

2. I assume you mean 11:49 AM. 11:49 AM to 6:49 PM is 7 hours. 6:49 PM to 7:12 PM is 23 mins. Total time is 7 hours 23 mins, or 7 hours to the nearest hour.

3. 2:25 PM to 3:25 PM is 1 hour, 3:25 PM to 3:35 PM is 10 mins. Total time is 1 hour 10 mins or 1 hour to the nearest hour.

4. 8:25 AM to 10:25 AM is 2 hours. 10:25 AM to 10:52 AM is 27 mins. Total time is 2 hours 27 mins or 2 hours to the nearest hour.

The trick is to count the number of hours first, then count the number of minutes remaining.
