A train 270 m long is moving at a speed of 24 kmph. It will cross a man coming from the opposite direction at a speed of 3 kmph in
Answer & explanation
Correct answer: option 4
Speed = \(\frac{ Distance}{ Time}\)
(24 + 3) x \(\frac{5 }{18}\)= \(\frac{ 270}{ Time}\)
(27) x \(\frac{5 }{18}\)= \(\frac{ 270}{ Time}\)
(3) x \(\frac{5 }{2}\)= \(\frac{ 270}{ Time}\)
\(\frac{15 }{2}\)= \(\frac{ 270}{ Time}\)
Time = \(\frac{ \text{270 x 2 }}{15}\)
Time = 36 sec
