ball is dropped from a height of 32 meters. When it hits the ground, it bounces back to half the height it fell from, and then falls again. Repeatedly, each time it bounces back to half the height of the previous drop. Excuse me, how long did the ball travel when it reached the ground for the third time?
一个球被人从32米高的地方扔下，它落到地面后，反弹的高度是落下高度的一半，然后又再次落下，如此反复，每次反弹的高度都是前一次落下高度均一半．请问，这个球在它第3次到达地面时，它一共经过了多长的距离？
