Solution

The correct option is B
$10 m / s$

Step 1: Given
Distance, $s = 54 k m = 54000 m$
Time, $t = 90 m i n s = 5400 s$
Step 2: Formula used
$S p e e d = \frac{D i s \tan c e}{T i m e}$
Step 3: Determine the speed
$S p e e d = \frac{D i s \tan c e}{T i m e} = \frac{54000}{5400} = 10 m / s$
Hence, option B is the correct option.
