Solution

First convert $k m / h r$ to $m / s e c$
$\frac{k m}{h r} = \frac{1000 m}{60 \times 60 s e c} = \frac{1000}{3600} \frac{m}{s e c} = \frac{5}{18} \frac{m}{s e c}$
From the above conversion, we can say that $\frac{k m}{h r} = \frac{5}{18} \frac{m}{s e c}$
So to convert $k m / h r$ to $m / s e c$ we multiply the given number by $\frac{5}{18} m / s e c o r 0.28 m / s e c$
Now,
$54 k m / h r = 54 \times \frac{5}{18} m / s e c = 15 m / s e c$
Therefore we can say that $54 k m / h r$ is $15 m / s e c$

Convert a speed of 54 km per hour into meter per second.

First convert km/hr to m/seckmhr=1000m60×60sec=10003600msec=518msecFrom the above conversion, we can say that kmhr=518msecSo to convert km/hr to m/sec we multiply the given number by 518m/secor0.28m/sec Now, 54km/hr=54×518m/sec=15m/secTherefore we can say that 54km/hr is 15m/sec
