September 12, 2021 | education

| Task data: R (radius of the circular route) = 6 km (in SI R = 6000 m); t (time for a given racing motorcycle to complete each lap) = 12 min (in SI t = 720 s).

The speed of movement of this racing motorcycle is calculated by the formula: V = S / t = 2 * Π * R / t.

Let’s calculate: V = 2 * 3.14 * 6000/720 = 52.33 m / s (188.4 km / h).

Answer: This racing bike is traveling on the ring track at a speed of 188.4 km / h.
