Discussion :: Problems on Trains

A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Answer : Option D
Explanation :
speed = \([60 * \frac { 5 } { 18 } ]\)m/sec =\([ \frac { 50 } { 3 } ]\)m/sec
Length of the train = (Speed x Time).
Length of the train =  \(\left(\frac{50}{3}\times9\right)\)  m = 150
