The speed of the bus is 20m / s and the speed of the racing car is 360 km / h. How many times is the speed of the racing car faster than the speed of the bus?
Initial data: V1 (bus speed) = 20 m / s; V2 (racing car speed) = 360 km / h.
1) Let’s translate the value of the speed of the racing car in the SI system (m / s): V2 = 360 km / h = 360 * 1000/3600 m / s = 100 m / s.
2) Let’s compare the speed of a racing car and the speed of a bus: k = V2 / V1 = 100/20 = 5 times.
Answer: The speed of a racing car is 5 times faster.
