Question

Mario worked from 8:25 to 12:45 yesterday. Today he will work from 11:20 to 3:10 How many hours did he work in all?

Answer 1

Answer: 8 hrs and 10 mins

Explanation:

1245 - 825 = 420 (4 hours and 20 minutes)

11:20

12:20 (1 hour)

1:20 (2 hrs)

2:20 (3 hrs)

3:10 (3 hrs 50 mins)

4 hrs + 3 hrs = 7 hrs

20 mins + 50 mins = 1 hrs and 10 mins.

Total = 8 hrs and 10 mins.
