Question

A car is moving at an average speed of $40\frac{2}{5}$ km/hr. How much distance will it cover km/hr. How much distance will it cover in $7\frac{1}{2}$ hours ?

Answer 1

Distance covered in 1 hour = $40\frac{2}{5}=\frac{202}{5}km$

$\therefore$ Distance covered in $7\frac{1}{2}$ hours

$=\frac{202}{5}\times 7\frac{1}{2}km=\frac{202}{5}\times \frac{15}{2}=\frac{202\times 15}{5\times 2}km=\frac{3030}{10}km=303kmAns.$
