Sharon drops a rubber ball from a height of 160 feet. Every bounce sends the ball half as high as it was before. What is the total vertical (up and down) distance the ball has traveled, from the moment it is dropped to the moment it hits the floor for the fourth time?
​

Answer 1

• 440 ft

Explanation:

Ball dropped and we start count from that moment:

• 160 ft down
• 80 ft up and down
• 40 ft up and down
• 20 ft up and down, end

Total distance:

• 160 + 80*2 + 40*2 + 20*2 = 440 ft
