Jack usually mows his lawn in 5 hours. Marilyn can mow the same yard in 2 hours. How mch time would it take for them to mow the lawn together?
Answer provided by our tutors
let 'x' represent the amount of time it takes to mow the lawn together:
1/x = 1/5 + 1/2
x=1.42857
So it would take approximately 1.4 hours to mow the lawn together, roughly the same as 1 1/2 hours.
