To determine the speed of the cyclist under consideration, who moved uniformly (the speed is constant) and rectilinear (the path is equal to the movement), we use the formula: V = S / t, where S is the distance the cyclist moved (S = 10 km, in SI S = 10 * 10 ^ 3 m); t – duration of movement (t = 15 min, in SI system t = 900 s).

Calculation: V = S / t = 10 * 10 ^ 3/900 = 11.11 m / s (40 km / h).

Answer: The cyclist’s desired speed was 40 km / h.
