Question

Molly spend 1 hour 19 minutes less than lane reading last week lane spent 47 minutes less than Pete Pete spent 3 hours reading how long did molly spend reading

Answer 1

54 minutes

Explanation:

For easier computation convert hours minutes to all minutes as follows:
h hours and m minutes = (h x 60 + m) minutes

Peter read the most for3 hours

3 hours = 60 x 3 = 180 minutes

Lane read for 47 minutes less than Peter
Time that Lane spent on reading = 180 - 47 = 133 minutes

Molly spent 1 hour and 19 minutes less than Lane spent on reading
1 hour and 19 minutes = 1 x 60 + 19 = 79 minutes

So Molly spent 79 minutes less than Lane on reading
Actual time Molly spent on reading = 133 - 79 = 54 minutes
