Question

A car travels $120\text{km}$ in three hours. On average, the distance covered in an hour is $\text{km}$.

Answer 1

Total distance covered $=120\text{km}$
Number of hours taken $=3$

Assumng equal distance covered in each hour,
$\text{Distance covered in an hour}=\frac{\text{Total distance covered}}{\text{Total number of hours}}$

$=\frac{120}{3}\text{km}$
$=\frac{3\times 4\times 10}{3}\text{km}$
$=40\text{km}$
