A train of length 250 m runs at a speed of 70 km/hr. What will be the time taken to cross any stationary object standing at the railway station? Choose the correct option: A) 20 sec B) 17.23 sec C) 12.86 sec D) 9.5 sec E) 8.5 sec
EXPLANATION:   Length of train = 250 m, speed of train = 70 km/hr   Length of train is always considered as distance, and hence here distance = 250 m   1) First convert speed of km/hr into m/s   Speed of train = 70 x	5	= 19.44 m/s   18   2) We know that,   Speed =	Distance /Time   Time taken to cross stationary object =	250 / 19.44   Time taken to cross stationary object= 12.86 sec   ANSWER IS 12.86 sec
