Question 428211
Jack usually mows his lawn in 8 hours. marilyn can mow the same yard in 6 hours. How much time would it take for them to mow the lawn together?
.
Let x = time (hours) it takes for both
then
x(1/8 + 1/6) = 1
multiplying both sides by 48:
x(6 + 8) = 48
14x = 48
x = 48/14
x = 3.43 hours
or
x = 3 hours and 26 minutes
