Two trains, A and B, leave their respective starting points at the same time and travel in opposite directions. They travel at constant speeds, and pass at point M. One travels at twice the speed of the other. If one of the trains leaves five minutes late they pass at a point 2 miles from point M.
What is the speed of the slow train, in miles per hour?
(In reply to

K is a constant, representing the ratio of speeds of the two trains.
K = (Fast Train speed)/(Slow Train speed)
It can be seen from the formula that K will never be less than 1
