A train running at the speed of 90 km/hr crosses a pole in 15 seconds. What is the length of the train?
Select the correct option.
A) 325  B) 350  C) 375  D) 400  E) 425

Rationale: "speed = ( 90 x ( 5 / 18 ) m / sec = ( 25 ) m / sec . length of the train = ( speed x time ) . length of the train = ( ( 25 ) x 15 ) m = 375 m c"
Answer: C
