Question 50

Two students, Amara and Leo, want to estimate the average speed of a toy car rolling down a wooden ramp.

Amara measures the length of the ramp by lining up plastic building blocks end-to-end.

She records:

'Length = 24 blocks'

Leo estimates the time taken for the toy car to travel this distance by reciting a short nursery rhyme repeatedly at what he feels is a steady pace.

He records:

'Time = 3 recitations'

Give three ways the students could improve their experimental procedure to obtain a more accurate value for the speed of the car.
