Two trains are traveling on parallel tracks are going towards eachother froma distance of 150km. One is moving at 60kmperhour, the other at 110kmperhour.
After how many hours with the trains pass eachother?
-----------
Add the speeds when the directions are opposite.
r = 60 + 110 = 170 km/hr
----
d = r*t
t = d/r
