You can put this solution on YOUR website! John can run a certain course in 9 min and henry can run it in 6 min.
If they start opposite ends and run toward one another, how long will
they run before they meet?
:
Let d = the distance of the course
Let t = time for them to meet
:
Write a speed equation, speed = dist/time
:
John's speed + Henry's speed = combined speed + =
:
Multiply equation by 18t, results
2dt + 3dt = 18d
:
Divide thru by d
2t + 3t = 18
5t = 18
t =
t = 3.6 minutes for them to meet
