Question

paul left for school at 7:25 am. he returned home at 3:15 pm. how long was paul away from home? 8 hours 50 minutes 8 hours 10 minutes 7 hours 50 minutes 4 hours 10 minutes

Explanation:

Step1: Convert 3:15 PM to 24-hour format

3:15 PM is 15:15 in 24 - hour time.

Step2: Calculate the time difference

Subtract the start time (7:25 AM or 7:25 in 24 - hour time) from the end time (15:15).
First, calculate the minutes: 15 - 25. Since 15 < 25, we borrow 1 hour from the hours place. 1 hour = 60 minutes, so 15+60 = 75 minutes. Then 75 - 25 = 50 minutes.
Then calculate the hours: 15 - 1 (because we borrowed 1 hour) - 7 = 7 hours.
So the total time away is 7 hours 50 minutes.

Answer:

7 hours 50 minutes (the option with "7 hours 50 minutes")
