I find myself at the mercy of ATOT once again
I've been doing this problem for an hour and I can't figure it out... the answer is in the back of the book but I can't produce those answers at all. I'd love to list all that I've tried but it would take me an hours worth of work to do that, lol. Here's the problem:
A freight train and an express train leave towns 390 km apart, traveling toward one another. The freight train travels 30 km per hour slower than the expess train. They pass one another 3 hours later. What are their speeds?
So far all I've got is this equation:
x + y = 130 (Got that from 390 / 3, obviously! )
Thanks in advance to all those who prove helpful to my endeavor!
