she can complete the route in 11 minutes. It takes 33 minutes to cover the same distance when she walks. If her jogging rate is 6 mph faster than her walking​ rate, find the speed at which she jogs.

Question

speed at which she jogs

Answer 1

Let j be the jogging speed in mph.

11 minutes is 11/60 hr, 33 minutes is 33/60 hr.

11j/60=33(j-6)/60, j=3j-18, 2j=18, j=9 mph.

Her jogging speed is 9mph.
