Express the speed $72 k m / h r$ in $m / s$ ( $metres per second$ ).

Open in App

Solution

Conversion of units:
We know that to change the speed in $k m / h r$ to speed in $m / s$ , we have to multiply by $\frac{5}{18}$ . So, we can write,
$72 \times \frac{5}{18} = 20 m / s$
Hence, we can express speed $72 k m / h r$ as $20 m / s$ .
