A motorcyclist moves at a speed of 54 km / h, and a pedestrian at a speed of 2 m / s.

A motorcyclist moves at a speed of 54 km / h, and a pedestrian at a speed of 2 m / s. How many times is the speed of a motorcycle longer than the speed of a pedestrian?

To compare the speed of a motorcyclist and the speed of a pedestrian (the speed is 2 m / s), we translate the speed of a motorcyclist, which is 54 km / h, into the system units of speed measurement in m / s in accordance with the international SI system:
54 km / h (1 km = 1000 m, 1 h = 3600 s) = 54 * 1000/3600 = 54000/3600 = 15 m / s.
V2 / V1 = 15/2 = 7.5 p.
Answer: The speed of the motorcyclist is 7.5 times the speed of the pedestrian.
