Question

A bus covers $24\mathrm{km}$ in $\frac{2}{5}$ hours. How much distance will it cover in $2$ hours?

Answer 1

Given
In $\frac{2}{5}\mathrm{hours}$bus covers$24\mathrm{km}$.
$\therefore$ Distance covered by the bus in $1$ hour = $\frac{24\times 5}{2}\mathrm{km}$ = $60\mathrm{km}$
So distance covered by the bus in $2$ hours = $2\times 60\mathrm{km}$ =$120\mathrm{km}$.
