A goods train runs at the speed of 72 km/hr and crosses a 290 m long platform in 26 sec. What is the length of the goods train?	Choose the correct choice from the following choices:
A) 278
B) 166
C) 151
D) 230
E) 109

Rationale: "speed = 72 * 5 / 18 = 20 m / sec . time = 26 sec . let the length of the train be x meters . then , ( x + 290 ) / 26 = 20 x = 230 m . answer : d"
Answer: D
