Question

Melissa returned home from mowing lawns at 4:15 P.M. It took 1 3/4 h to mow the first lawn. The second and third lawns she mowed each took 1 1/5 h. She took only a 45-min break. When did Melissa begin mowing the first lawn?

Answer 1

12:33 P.M

Answer 2

no

Answer 3

11:21 A.M

Answer 4

1.75 hour for the first lawn
1.2 hour for second lawn
1.2 hour for third lawn
0.75 hour break
Total time of mowing lawns + break = 4.9 hours = 4 hours and 54 minutes
What is 5 hours before 4:15 pm? Then add 6 minutes to that.

Answer 5

1 h = 60 min
1 3/4 = 60 + 45 = 95 min
1 1/5 = 60 + 12 = 72 min

95 min + 72 min + 72 min = 293 min = 4,88h

4h = 4h
0,88 h = 52 min

4.15PM - 4h. 52 min = is the solution
