Two trains, 130 and 110 metres long, while going in the same direction, the faster train takes one minute to pass the other completely. If they are moving in opposite direction, they pass each other completely in 3 seconds. Find the speed of trains.  Choose the correct choice:
A) 30 m/s, 40 m/s
B) 32 m/s, 48 m/s
C) 40 m/s, 44 m/s
D) 38 m/s, 42 m/s
E) None of these
Let speed of trains are S1 m/s and S2 m/s.   Then, s1 - s2 = 130+110/60=4 ....(i)   and s1 + s2 = 130+110/3=80....(ii)   on solving (i) and (ii), we get   S1 = 42 m/s , S2 = 38 m/s   Answer 38 m/s, 42 m/s
