Question

A car covers a distance of $30\frac{5}{8}$ km in $2\frac{1}{2}$ hours. How much distance will it cover in 1 hour?

Answer 1

Distance covered in $2\frac{1}{2}$ hours $=30\frac{5}{8}$ km
$\therefore$ Distance covered in 1 hour
$=30\frac{5}{8}÷2\frac{1}{2}$

$=\frac{245}{8}÷\frac{5}{2}$

$=\frac{245}{8}\times \frac{2}{5}$

$=\frac{49}{4}$

$=12\frac{1}{4}km$
