It takes Aaron about 1 hour to mow 2 acres.
Aaron’s rate for mowing lawns is 0.5 acres per hour.
The ratio of acres to time is 5 acres to 3 hours.
The rate to mow a lawn is 0.6 hours per acre.

Well, the slope is 1/2 (2.5-1.5, and 5-3) But you now need to divide 1/2. This will get you 0.5 acres per hour. That is the rate.
