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.
Note that the steps in total are 16. She takes the same amount of steps forward and backward, and so divide 16 by 2
She takes 8 steps forward, and 8 steps backward.
hope this helps
