A cyclist travels at a speed of 5 m / s, and a car at a speed of 108 km / h.

A cyclist travels at a speed of 5 m / s, and a car at a speed of 108 km / h. How many times the speed of a car is greater than the speed of a cyclist?

In order to solve this problem, you need to learn how to convert km / h to m / s. There are 60 seconds in one minute, and 60 minutes in one hour, which means in one hour 60 × 60 = 3600 seconds. One kilometer is 1000m. So, to convert km% h to m / s, you need to multiply by 1000 and divide by 3600 or divide by 3.6.

Let’s convert 108 km / h to m / s

V = 108 / 3.6 = 30 m / s.

Next, we compare the two speeds:

30/5 = 6 times

Answer: the speed of the car is 6 times the speed of the cyclist.
