You can put this solution on YOUR website! Jill is 13.5 kilometers away from Joe.
Both begin to walk toward each other at the same time.
Jill walks at 3 kilometers per hour.
They meet in 3 hours. How fast is Joe walking?
:
When they meet the total distance they have traveled will be 13.5 km
Let s = Joe's walking speed
:
3(3) + 3s = 13.5
9 + 3s = 13.5
3s = 13.5 - 9
3s = 4.5
s =
s = 1.5 km/hr is Joe's walking speed (slow, not very anxious to meet her it seems)
