A runner traveled 3 mi in the same time that a cyclist traveled 5 mi. The speed of the cyclist was 2 mph greater than that of the runner. What was the​ cyclist's speed?

2+x/x = 5/3

cross multiply

3(2+x)=5x

distribute

6+3x=5x

6+3x-3x=5x-3x

6=2x

6/2=2x/2

x=3

The runners' speed was 3 miles per hour and the cyclists' speed was 5 miles per hour
