(P/S) the total distance [#permalink]  10 Dec 2007, 05:19
It sounds simple, but I failed to get the right answer. Please let me know the solution to get the right number..

Q. A ball is dropped from a height of 36 meters. It rebounds 2/3 of its fallen distance. And what is the total distance it has moved until it drops three times to the ground?

The question sounds somewhat strange bc it has been translated..
The OA that I been given is 116.

36+2*(36*2/3)+2*(36*2/3*2/3)=36+2*24+2*(24*2/3)=36+48+32=116
I suppose that you forgot to multiply on 2 - this is the distance of the ball comming not only up, but also down.

dropped: 36
first bounce up+back down: 36*2/3=24+24
second bounce up and back down: 24*2/3=16+16
so three drops total:
36+24*2+16*2=116

1st time:
36 down = 36

2nd time:
2/3*36 = 24 up and 24 down = 48

3rd time:
2/3*24 = 16 up and 16 down = 32

Total = 36+48+32 = 116
