Question

Convert 54km/h to m/s.
15

Open in App

Solution

The correct option is A 15
1 km = 1000 m
1 hour = 60 min = 3600 s

So,
$1 k m / h = \frac{1000}{3600} m / s = \frac{5}{18} m / s$

For converting speed from km/h to m/s, we multiply km/h by $\frac{5}{18}$ .

$∴ 54 k m / h r = 54 \times \frac{5}{18} = 15 m / s$
