If 900 m long train crosses 700 m long platform in 1 minute, then speed of the train in kilometer per hour is:
Answer & explanation
Correct answer: option 2
Total distance traveled by train = Length of train + length of platform = 900 +700 = 1600 m
Time = 1 min = 60 sec
Speed of train = \(\frac{distance}{time}\) = \(\frac{1600}{60}\) = \(\frac{80}{3}\) m/sec
Speed of train = \(\frac{80}{3}\) × \(\frac{18}{5}\) km/hr = 96 km/hr
