Two trains are approaching each other at 60mph each. The length
of each train is 1/6 miles. When the two locomotives(engines) meet,
how many seconds will it take for them to pass each other completely?

• 10 Sec
  
  As their relative speed is 120mph
  and total distance to be covered is 1/6+1/6=1/3miles
  
  So, Time req= !/3*120 Hours
  =10sec

• distance=1/6+1/6=1/3
  relative speed of two trains in opposite direction is 60+60=120
  d=s*t
  t=d/s=(1/3)/120=1/360hrs=1/6min=10sec
