Question

the speed of car is 72km/h express it on m/s according to ICSE syllabus ​

Answer 1

Answer:

20m/s

Explanation:

speed of car = 72km/s

in m per second speed of car = 5*72/18 = 20m/s

Answer 2

ANSWER WITH FULL EXPLANATION

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

x km/h = (x*\frac{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 \frac{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*\frac{5}{18}) m/s = 20 m/s

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