Question

A car covers a distance of $160\text{km}$ between two cities in $4\text{h}$. What is the average speed of the car?

Answer 1

Given, $\text{Total distance covered}=160\text{km}$
$\text{Total time taken}=4\text{hr}$
To find, Average speed
$\text{Average speed}=\frac{\text{Total distance covered}}{\text{Total time taken}}=\frac{160\text{km}}{4\text{h}}$

So, the average speed of car is $40km{h}^{-1}$ .
