A train 360 m long runs with a speed of 45 km/hr. What time will it take to pass a platform of 190 m long? Choose the correct choice from the following options
A) 38 sec	B) 35 sec	C) 44 sec	D) 40 sec	E) 50 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 + 190 = 550 meter time taken to cross the platform = 550 / ( 25 / 2 ) = 550 × 2 / 25 = 44 seconds answer : option c"
Answer: C
