How would I do this:
Two trains approach each other on parallel tracks. The train traveling East is moving 151.0 km/hr with respect to the ground and the train traveling West is moving 151.0 km/hr with respect to the ground. If they are initially 5.9 km apart, how long will it be before they pass each other?
