Question

Zeno is walking in a straight line. With each step, he covers half the remaining distance between him and the end of his path, which is a total of 8 feet. After 4 steps, he will have walked _____ feet.

Answer 1

8 foot path

1st step = 8/2 = 4ft
2nd step = 4/2 = 2ft
3rd step = 2/2 = 1ft
4th step = 1/2 = 1/2ft

So he covered 7 1/2 ft (or 7.5ft)
