Luckily, I’ve never had that question on any maths test, though I do know how to solve it given enough information.
Do those questions ever tell you how far away each city is from one other, or are you just supposed to know that? Also, do the tracks go in a straight line the whole distance, and do they need to slow down on any stretches of track?
From what I call answering similar test questions in Algebra 1:
The questions assume a straight line, constant velocity, and give you the distance. What’s tested is the ability to make an algebraic equation for each train representing how far each will have traveled over a given time period, and typically find the time that they will intersect.
