Solution

The correct option is A $1.620$ km
$d i s t a n c e = s p e e d \times t i m e$
$t i m e = 2 m i n u t e s$
$\Rightarrow 2 m i n u t e s = \frac{1 \times 2}{60} = \frac{1}{30} h r$

$s p e e d = 13.5 m / s e c$
$\Rightarrow 13.5 m / s e c = \frac{13.5 \times 18}{5} = 48.6 k m / h r$

$\Rightarrow d i s t a n c e = 48.6 \times \frac{1}{30}$
$\Rightarrow d i s t a n c e = 1.620 k m$
