Question

(01.01 LC)A dancer took forward and backward steps of equal length during a dance. After taking 16 steps total, she was back at her starting position. How many steps did the dancer take in the forward and backward directions?

Answer 1

Since the steps are the same size, and she ended up where she started, she must have taken the same number of steps forward as she took backward.

16/2 = 8

She took 8 steps forward and 8 steps backward.

Answer 2

Note that the steps in total are 16. She takes the same amount of steps forward and backward, and so divide 16 by 2

16/2 = 8

She takes 8 steps forward, and 8 steps backward.
