Joy performs an investigation in which she makes a wooden ramp that can be adjusted to different heights. For her first trial, she adjusts the ramp to a particular height marked X in the image and applies a force on a toy car to slide it down the ramp.
Joy observes that it takes 1.1 s for the car to reach the bottom of the ramp. For her second trial, Joy adjusts the height of the ramp to one of the four marked positions and pushes the toy car with the same force. Joy observes that it takes 0.9 s for the toy car to reach the bottom of the ramp.

A. height 1
B. height 2
C. height 3
D. height 4
