To calculate the speed of the cyclist, we apply the formula: V = S / t, where S is the distance covered by the cyclist (S = 900 m); t is the duration of movement (k = 30 min, in the SI system t = 1800 s).
Let’s make a calculation: V = S / t = 900/1800 = 0.5 m / s.
Answer: The speed of the cyclist is 0.5 m / s.
