Jill is 13.5 kilometers away from joe. both begin to walk toward each other at the same time. jill walks at 2 kilometers per hour. they meet in 3 hours. how fast is joe walking?

Respuesta :

In order to answer this questions we need to calculate the Speed of the object.


In this case, distance between Jill and Joe=d=30km


Speed of Jill=2km/h


Time it takes for Jill and Joe to meet = t  = 3h


Distance covered by Jill= 2km/h * 3h =6km



Distance covered by Joe= d-6km= 30km-6km=24km



Speed of Joe = 24km/t=24km/3h=8km/h



Joe is walking at 8km/h
