Answer 2

Answer:

ANSWER WITH FULL EXPLANATION

If a speed is given xx km/h, then the formula to convert the speed from km/h to m/s is

xx km/h = ( x * 5/18)m/s

In other words, if you want to convert the given speed from km/h to m/s, then multiply the given number by 5/18 and put "m/s" after it.

The speed of a car is 72 km/h.

Converting the speed into m/s

72 km/h = ( 72 * 5/18 ) m/s = 20 m/s

∴ The speed of the car (expressed in m/s) is 20 m/s.
