Question

Suppose you drop a ball from a window 25 meters above the ground. The ball bounces to 75% of its previous height with each bounce. What is the total number of meters (rounded to the nearest tenth) the ball travels between the time it is dropped and the 10th bounce?

133.7 meters
163.7 meters
185.0 meters
188.7 meters

Answer 1

75% of 25 is 25*.75 which equals 18.75 and then you move the decimal place so you would get 187.5 which is close to 188.7

Answer 2

thanks!
