A train 360 m long runs with a speed of 45 km/hr. What time will it take to pass a platform of 390 m long?	Select the correct option:
A) 38 sec
B) 35 sec
C) 44 sec
D) 40 sec
E) 60 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 + 390 = 750 meter time taken to cross the platform = 750 / ( 25 / 2 ) = 750 × 2 / 25 = 60 seconds answer : option e"
Answer: E
