Question 1088227: Two trains 245m and 315m long are travelling towards each other at 90km/h and 54km/h respectively on parallel lines. How long do the trains take to pass one another from the time they meet each other? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 245+315=560 m
90+54=144 km/h
560m/144000 m/h=0.00388888888888888888888888888889 hrs
0.00388888888888888888888888888889 hrs x 3600 sec/hr=14 seconds
