Q.
A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?
A.
230 m
B.
240 m
C.
260 m
D.
270 m
View Answer
Correct choice: D
Explanation:
Speed =[ 72 x (5/18) ]m/sec= 20 m/sec. Time = 26 sec. Let the length of the train be x metres. Then,[ (x+250)/26 ]= 20 => x + 250 = 520 => x = 270.
