For 5h 30min. the cyclist covered a distance of 99 km. What was the average speed of the cyclist?

If we assume that the speed of the cyclist along the entire path was constant, then the average speed of movement is calculated by the formula:

Vav. = S / t, where S is the path covered by the cyclist (S = 99 km = 99 * 10³ m), t is the time the cyclist moves (t = 5 h 30 min = 5.5 h = 19 800 s).

Let’s calculate the average speed of a cyclist:

Vav. = S / t = 99 / 5.5 = 18 km / h (Vav. = 99 * 10³ / 19 800 = 5 m / s).

Answer: The average speed of a cyclist is 18 km / h or 5 m / s.
