Question 373296: A rubber ball rebounds to half the height it drops. If the ball is dropped from a rooftop 18 m above the ground, what is the total distance traveled by the time it hits the ground the third time?
I appreciate the help, I am stuck on how to solve this. Math has never been my strong point!

Okay, let's go through this exercise.
The ball is dropped from 18 meters.
It bounces up to 9 m, and then hits the ground a second time.
This time it bounces up to 4.5 m and then hits the ground a third time.
So we actually need to add up 5 different distances to get the total.
So for total distance traveled, we should have:
18+9+9+4.5+4.5=45 meters
The ball should have traveled a total distance of 45 meters.
If you draw a picture it should help quite a bit.
I hope this helps!
