Question

If a passenger train departs station x traveling at light speed and another train leaving station y at 1 mile an hour, at what point will they collide? (you many use your calculator for this problem)

Answer 1

It really depends are x & y on the same track, are they going in the same direction or opposite directions? Is train y Thomas the tank engine and train X the monorail from Vegas?? Too many variables, I say that it is highly improbable that they will collide in this century.

Answer 2

first, the passenger train cannot travel at "light speed." It's not possible...

But even imagining that it could, there is not enough information given to answer this question.

We would need to know:

1) Where station x and station y are relative to each other
2) the relative velocities of station x and station y
3) at what time does each train depart its station, and
4) in what direction is each train headed?

Another relevant factor, since they are trains and presumably on tracks, is whether the tracks intersect. If they don't the trains will never collide.
But as given, this "question" cannot be answered.

p.s. calculators are bad for your brain.

Answer 3

They will never collide.
