Jill is 11 kilometers away from Joe Both begin to walk towar

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?

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
