With what speed the bike moved, if in 15 minutes it covered 5 km. The movement is considered uniform.

Initial data: t (time of movement of the cyclist) = 15 min; S (distance traveled by the cyclist) = 5 km; the cyclist’s movement is uniform (the cyclist’s speed is constant throughout the entire path).

SI system: t = 15 min = 15 * 60 s = 900 s; S = 5 km = 5 * 1000 m = 5000 m.

To calculate the constant speed of a cyclist, we use the following formula: V = S / t.

Let’s perform the calculation:

V = 5000/900 = 5.56 m / s.

Answer: The constant speed of the cyclist is 5.56 m / s.
