A student wants to find out whether the average speed of a toy car rolling down a ramp depends on the height of the ramp.
The student has a ramp, a toy car, a metre rule, a stopwatch and some blocks to raise one end of the ramp.
Describe a method the student could use.
Your answer should include how the student would calculate the average speed.
