A train 60 m long passes a platform 90 m long in 10 seconds. The speed of the train is
Answer & explanation
Correct answer: option 3
Speed = \(\frac{ Distance}{ Time}\)
Speed = \(\frac{\text{60 + 90}}{ 10}\)
Speed = \(\frac{150}{ 10}\)
Speed = 15 m/s
Speed in km/hr = 15 x \(\frac{18 }{ 5}\) km/hr
Speed in km/hr = 54km/hr
