Answer 2

Given:

The speed of car in 20 m/s then _______km/hr?

Answer:

To convert a speed from m/s to km/hr we need to multiply the number by $\frac{18}{5}$.

So, to convert 20 m/s into km/hr we will multiply it by $\frac{18}{5}$ .

$\frac{20}{1}$ × $\frac{18}{5}$ =  $\frac{360}{5}$ = 72 km/hr

Hence, The speed of the car in km/hr is 72 km/hr
