Question

A train passes two persons who are walking @ 5 m/sec & 10 m/sec

respectively in opposite direction in which train is moving, in 6 sec and 5 sec

respectively. Find the length of train​

Answer 1

Answer:

Correct Answer:

D) 600 m

Description for Correct answer:

Let the speed of the train be x.

According to the question,

(x+10)×12=(x+20)×10

=> 6x+60=5x+100

=> x=100−60=40m/s

Therefore, Length of the train = (x+10×12)

= (40+10)×12 = 600 m
