Line Graph Questions At what angle was the ramp when the toy car travelled 15cm? How far did the toy car travel when the ramp was at 30°? At what angle was the ramp when the toy car travelled 10cm? When the ramp was at 55° how far did the toy car travel? What do you think will happen if the ramp is set at 90°?
