A rubber ball dropped on a hard surface takes a sequence of bounces, each one 3/5 as high as the preceding one. If this ball is dropped from a height of 10 feet, what is the total vertical distance it has traveled after it hits the surface the 5th time? Be sure to account for both drop and rebound distances.

It is a geometric sequence, each time the ball bounces, it is 3/5 as high as the previous bounce.

@Kayy_Drizzyy I am getting offline for a bit, the picture should help you visualize the situation and hopefully you have been helped enough to the point where you can feel comfortable trying to solve this. Otherwise, good luck in hoping someone comes in and can help you find a solution. Best of luck in your math.

PS The picture is not complete, see the "..."? That shows that there is bounces between the beginning and end of the picture, I just did what I could to get you started. Again, best of wishes.
