Answer 2

1) Initial fall => 46 yards


2) First bounce = > rising 46/2 yards and falling the same => 23*2 = 46


3) Second bounce => rising 23/2 yards and falling the same => 11.5*2 = 23


4) Third bounce => rising 11.5/2 yards and falling the same => 5.75 * 2 = 11.5


5) Fourth bounce => rising 5.75 / 2 yards = 2.875


Sum = 46 + 46 + 23 + 11.5 + 2.875 = 129.375


Answer: 129.375 yd
