Question 575167: Jill is 10 kilometers away from joe. Both begin to walk toward each other at the same time. Jill walks at 1km/hr. they meet in 4hr. How fast is how walking? Answer by chana(69) (Show Source):
You can put this solution on YOUR website! Jill is 10 kilometers away from joe. Both begin to walk toward each other at the same time. Jill walks at 1km/hr. they meet in 4hr. How fast is how walking?
sol:
let the speed of joe is x km/hr.
distance moved by jill + distance moved by joe = distance apart
distance = speed * time
so (1 * 4) + (x * 4) = 10
solving for x gives you speed of joe which is 1.5 km/hr
