A student wants to measure the average speed of a remote-control car.

The student estimates that one of her paces is 0.8 m.

She counts 50 paces between two chalk lines on a pavement.

She uses a smartphone stopwatch to measure the time the car takes to travel between the two chalk lines.

A diagram showing a remote-control car on a pavement between two parallel chalk lines. A student is shown pacing out the distance between the lines with a double-headed arrow labeled '50 paces'. Another student stands by the finish line holding a phone to time the car.

State two improvements the student could make to this method to get a more accurate value for the speed.
