At 3:25 p.m., two trains left Kalamazoo, Michigan. One train traveled westward at a constant rate of  miles per hour, while the other traveled eastward at a constant rate of miles per hour. If they are now miles apart, what time is it now? Write and solve an equation (or system of equations) to answer this question.

Distance = (rate)(time)
Write a distance equation for each train.

If the trains are miles apart, then their 'total distance' is . Use this to write an equation.

Note: The solution to this equation is not the answer to the question asked in the problem.
