43.A train 100 m long is running at the speed of 30 km/hr. Find the time taken by it to pass a man standing near the railway line.
A. 10 sec. B. 12 sec.
C. 14 sec. D. 16 sec.
Answer:
Speed of the train = (30 x 5/18)m/sec
= (25 / 3) m/sec.
Distance moved in passing
the standing man = 100 m.
Required time taken = 100 /( 25 / 3)
=(100 x 3 / 25) sec
= 12 sec.
