Question

The velocity of a car is 15 m/s. What is the velocity of the car in km/h?​

Answer 1

Answer:

54kmph

Explanation:

1 m = $10^{-3}$ km

1 sec = $\frac{1}{3600}$ hour

Now multiply this with the values of meters and seconds given in the question.

$\frac{15 * 10^{-3} }{1/3600}$

This will give us $15 * 10^{-3} * 3600$

On multiplying the values we get 54. Thus 54 km/h will be your answer.

Hope you understand :)
