Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 mph faster
than the westbound train. If the two trains are 320 miles apart after 2 hours, what is the rate of the eastbound train?
~~~~~~~~~~~~~~~~~~~~~~~
u + v = , (1) (u is the eastbound train speed)
u - v = 14. (2) (v is the westbound train speed)
Or
u + v = 160,
u - v = 14.
Add the two equations.
