A train 280 m long, running with a speed of 63 km/hr will pass an electric pole in :
Answer & explanation
Correct answer: option 2
Speed = \(\frac{ Distance}{ Time}\)
63 x \(\frac{ 5}{ 18}\) = \(\frac{ 280}{ Time}\)
\(\frac{ 315}{ 18}\) = \(\frac{ 280}{ Time}\)
Time = \(\frac{\text{280 Χ 18} }{ 315}\)
Time = 16 sec
