Question 829787: Maxine and Sammie have the same size lawn. Maxine can mow the lawn in 24 minutes and Sammie can mow the lawn in 36 minutes. If Maxine and Sammie begin to mow the lawn at the same time, at what time will Sammie have exactly twice as much lawn left to mow as Maxine?

The job is 1 lawn.
Maxine's rate is LAWN per MINUTE
Sammie's rate is lawn per minute

This is a problem of the type R*t=j, where R is work rate in jobs per time, t is time, j is the amount of jobs.

To examine for "job left to do", this is a difference between one whole job and amount of job done. You need to feel comfortable with this, before continuing this solution.
