Question

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?

Answer 1

Joe is walking at a speed of 2.5 kilometers per hour.

Step-by-step explanation:

In order to find Joe's walking speed, we need to first determine the total distance that Jill and Joe will cover before they meet. Since Jill walks at 2 kilometers per hour and they meet after 3 hours, Jill would have covered a distance of 2 km/hr * 3 hr = 6 kilometers. Since Joe is 13.5 kilometers away from Jill, this means that Joe would have covered a distance of 13.5 km - 6 km = 7.5 kilometers before they meet.

Therefore, Joe's walking speed is the distance covered divided by the time taken, which is 7.5 km / 3 hr = 2.5 kilometers per hour.

Answer 2

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
