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?
:
Let s = Joe's walking speed
:
write a distance equation: dist = time * speed,
the distances each person walks adds up to 13.5 km
:
Jill's dist + Joe's dist = 13.5 km
3(3) + 3s = 13.5
3s = 13.5 - 9
3s = 4.5
s =
s = 1.5 km/hr is Joe's crawling speed
:
:
Check; find the dist of each:
3(3) = 9 km
3(1.5)= 4.5 km
--------------
total 13.5 km
