A goods train runs at the speed of 72 km/hr and crosses a 80 m long platform in 26 sec. What is the length of the goods train? Choose the correct choice from the following options:
A) 382  B) 440  C) 278  D) 270  E) 881

Rationale: "speed = 72 * 5 / 18 = 20 m / sec . time = 26 sec . let the length of the train be x meters . then , ( x + 80 ) / 26 = 20 x = 440 m . answer : b"
Answer: B
