Question

Sasha returned home from mowing lawns at 4:15 p.m. It took 3/4h to mow the first lawn. The second lawn took 1h. She took a 30-min break between the two lawns. When did Sasha begin mowing the first lawn?

Answer 1

2:00

Explanation:

Count backwards from 4:15 p.m. One hour prior to that was at 3:15 p.m.

Her 30-minute break began at 2:45 p.m. Three fourths of an hour before that was at 2:00 p.m. Sasha began work on the first lawn at 2:00 p.m.

Answer 2

2:00 p.m.

Explanation:

3/4 hour is equal to 45 minutes. Add 30 minutes to that and you have 1 hour and 15 minutes. You will then add the final hour to that to get 2 hours and 15 minutes. Subtract that from 4:15 and you get 2:00.
