Two road crews are paving a straight section of highway. The first crew has completed paving 81 miles and is completing 2 additional miles per day. The second crew has only finished 77 miles but is covering 3 miles per day.

The maple tree that is 20 inches tall is growing 4 inches per month, whereas the oak tree that is 26 inches tall is growing 3 inches per month.
