Jill is 11 kilometers away from Joe. Both begin to walk toward each other at the same time. Jill walks 2.5 km/h.They meet in 2 hours. How fast is Joe walking? Solution let the speed of Joe = x km/h distance traveled by Jill in 2 hrs = speed * time = (2.5)(2) = 5 distance traveled by Joe = 2x since total distance traveled is equal to distance between them 5 + 2x = 11 2x = 6 x = 3 Joe is walking at the rate of 3 km /h.
