Two students attempt to measure the average speed of a radio-controlled toy car traveling along a straight outdoor pathway between two marker flags.
The distance between the two flags is measured as 80 m80\text{ m}80 m. Suggest an appropriate instrument that they might use to measure this distance.
The car travels from the first flag to the second flag. It takes 16 s16\text{ s}16 s to travel between the two flags.
Name an appropriate instrument that could be used to measure this time.
Describe the procedure for measuring this time.
Calculate the average speed of the toy car, including the unit.
