Two trains running in the same direction with a speed of 60kph and 50kph having lengths of 200m each. How long it will take the trains to completely pass each other(in seconds)?	Choose the correct choice:
A) 13.09
B) 32.17
C) 54.9
D) 112.98
E) 143.88
Relative speed of trains with respect to each other=60-50=

10kph=2.78m/s   Distance need to be covered=200+200= 
<gadget id="calculator">200+200</gadget>
<output>400</output>
400   Time taken to pass each other=400/2.78=143.88s   Answer: 143.88
