Question

Find the speed of a car (in km/hr) which covers a distance of 18 km in 20 minutes​

Answer 1

Answer:

speed = 54km per hour

Step-by-step explanation:

1 hour = 60min

18km = 20 min

18 X 3=60 min

54km = 60 min

Answer 2

Step-by-step explanation:

Distance, s = 18 km

Time, t = 20 m = 20/60 = 1/3 hours

Now,

speed v = s/t

Therefore, v = 18 / 1/3

Therefore, v = 18*3/1

Therefore, v = 54 km/hr

Hence,

The speed of a car which covers a distance of 18km in 20 minutes is 54 km/hr.

________________________________________

Also, even if 54 km/hr is a correct answer.

But,

This is physics, for finding answers there are specific formulas, it do not go like taking estimations. Formulas must be used, otherwise, you'll not get marks for just manual calculation.
