Two trains leaving from two station 50 miles away from each other with costant speed of 60 miles per hour, approaches towards each other on diffrent tracks. if lenght of each train is 1/6 mile. when they meet How much time they need to pass each other totally? Choose the correct choice:
A) 1/6 min B) 1/7 min C) 1/8 min D) 1/9 min E) 1/5 min
both are approaching each other relative speed=60+60=

120m/h   distance=50m   time=50/120=5/12hrs= 25 minutes to meet   now,   relative length of train= 1/6+1/6=1/3m   relative speed = 120m/h   time to cross both the trains= (1/3)/120=1/360 hrs   = 1/6 minutes   1/6 minNSWER:1/6 min
