b .based on the data, the faster the vehicle travels, the less time it will take to reach the destination.
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.
(3^2)3=27
27/3^x=3
3(3^x)=27
3^x=9
x=2
