Two trains 85 m and 75 m long are running in same direction with speeds of 62 km/hr and 44 km/hr respectively. In what time will the first train cross the second train ?	Pick one.
A) 12 sec
B) 32 sec
C) 82 sec
D) 92 sec
E) 13 sec
Explanation:   Given that,   1st train speed = 62 km/hr   2nd train speed = 44 km/hr   Hence the relative speed of two trains is   62-44=

18 km/hr m/s= 5 m/s.   There fore, the first train crosses the second train i.e (85+75)mts of distance with a speed of 5m/s in,   time = \frac{distance}{speed} \frac{(85+75)}{5} = 32 sec.   Answer: 32 sec
