Question 1:
A train 200 m long is moving with the speed of 50km per hour.
Find the time taken to pass a tree standing near the railway track.
A. 14 2/5 seconds
Feedback Speed of the train = 50km/hr = 50 x 5/18 m/sec = 250/18 m/sec
Length of the train = 200 m
Time taken to cross the tree = 200 / (250/18) = 200 x 18/250 = 72/5 = 14.4 seconds
Hence the answer is 14 2/5 seconds.
B. 15 seconds
C. 16 1/2 seconds
D. 17 seconds
