Question

Tim goes bungee jumping off a bridge over water. On his first fall, Tim travels 100 feet before bouncing and then rise to 3/5 of his previous fall. If this pattern continues, what distance did Tim travel after 8 bounce? Round to the nearest tenth (one decimal place)

Answer 1

414.6

Explanation:

assuming tim rises 3/5 after the very first fall (most likely what they meant in the question, if not, there is not enough information since there was no previous fall after the FIRST fall)

First fall, he traveled 100 feet and bouced back 3/5 which means 100×3/5= 60 feet. so now he is at 60 feet. continuing the same formula you would get ....

100 ft + 60 ft + 60ft (back to the bottom)+36ft+36ft+ 108/5ft + 108/5ft + 342/25ft + 342/25ft + 1026/125ft+ 1026/125ft + 3078/225ft ×2 + 9234/1125ft ×1 = 414.6

after the last bounce, you dont count the distance up.. (edited)

hopefully i got it right .. :)
