Plumber calling
On a particular day, John has four clients.
He takes 75 minutes to deal with Jill's plumbing, and she pays him $60.
He takes 60 minutes to deal with Jen's plumbing, and she pays him $50.
He takes 90 minutes to deal with Jane's plumbing, and she pays him $70.
He takes 105 minutes to deal with Jeanne's plumbing, and she pays him $85.
From which woman did he make the most money per hour?

The rate per hour from Jill = $60/1.25 hrs = $48 per hour
The rate per hour from Jen = $50/1 hr = $50 per hour
The rate per hour from Jane = $70/1.5 hours = $46.67 per hour
The rate per hour from Jeanne = $85/1.75 hours = $48.57 per hour
So Jen paid the most per hour.
