Student: A train running at the speed of 90 km/hr crosses a pole in 9 seconds. Find the length of the train.
Options:
(A) 225 meter
(B) 200 meter
(C) 250 meter
(D) 210 meter
(E) 230 meter.
Another student: Let's say, hmmm...
Speed = 90*(5/18) m/sec = 25 m/sec
Length of Train (Distance) = Speed * Time
(25) * 9 = 225 meter Final answer: (A).
