Q: A train running at the speed of 40 km/hr crosses a signal pole in 9 seconds. Find the length of the train ?

We know that S p e e d = d i s tan c e t i m e distance= speed * time ⇒ d = 40 × 5 18 × 9 d= 100 mts.

90 mts
150 mts
120 mts
100 mts

Correct Answer: 100 mts

Explanation:

We know that $S p e e d = \frac{d i s \tan c e}{t i m e}$

distance= speed * time

$\Rightarrow$ $d = 40 \times \frac{5}{18} \times 9$

d= 100 mts.
