Problema Solution
Jack usually mows his lawn in 6 hours. Marilyn can mow the same yard in 5 hours. How much time would it take for them to mow the same lawn together?
Answer provided by our tutors
1/6 --> part of work completed by Jack in an hour
1/5 --> part of work completed by Marilyn in an hour
1/6 + 1/5 = 11/30 ----> part of work they completed if they work together
(1/6 + 1/5) x 1
x = 30/11 or 2 11/12 ----> hours to complete mowing the lawn.
