Solution

The correct option is A
$\frac{18}{5}$

$1 h o u r = 3600 s e c o n d s$
$∴ 1 s e c o n d = \frac{1}{3600} h o u r$
$1 k m = 1000 m e t r e$
$1 m e t r e = \frac{1}{1000} k i l o m e t r e$
Hence 1 $m / s$ = $\frac{\frac{1}{1000}}{\frac{1}{3600}}$ $k m / h r$
= $\frac{18}{5}$

1 $m / s$ = ____ $k m / h r$

The correct option is A
$\frac{18}{5}$

$1 h o u r = 3600 s e c o n d s$
$∴ 1 s e c o n d = \frac{1}{3600} h o u r$
$1 k m = 1000 m e t r e$
$1 m e t r e = \frac{1}{1000} k i l o m e t r e$
Hence 1 $m / s$ = $\frac{\frac{1}{1000}}{\frac{1}{3600}}$ $k m / h r$
= $\frac{18}{5}$
