A student wants to measure the average speed of a cyclist.
The student estimates that one of his own steps is 1 m.
He counts 100 steps between two posts on a track.
He uses a stopwatch to measure the time the cyclist takes to travel between the two posts.
Figure 2 shows the set‑up used to measure the average speed.
State two improvements the student could make to this method.

(3)
A technician measured the frequency of the water wave in part (a) by counting how many waves passed him in 15 s.
Explain why this would not be a suitable method for measuring the frequency of the seismic wave in part (b)(ii).
