A train 360 m long runs with a speed of 45 km/hr. What time will it take to pass a platform of 290 m long?  Options.
A) 38 sec	B) 35 sec	C) 44 sec	D) 40 sec	E) 52 sec

Rationale: "explanation : speed = 45 km / hr = 45 × ( 10 / 36 ) m / s = 150 / 12 = 50 / 4 = 25 / 2 m / s total distance = length of the train + length of the platform = 360 + 290 = 650 meter time taken to cross the platform = 650 / ( 25 / 2 ) = 650 × 2 / 25 = 52 seconds answer : option e"
Answer: E
