Right, it’s a third grade question. Let’s make it more fun. .. the 2nd train is going West… not South.
So, yeah. … some of you will jump right in. ..Pythagorus and all that. ..
25 squared plus 20 squared. .Square root of that. ….uh hum.. uh hum. ..
Only. …Hold up there, cowboy. ..
BIG asumptions there….
For one. .who said the tracks were straight?
if the first train travels 25 miles of switchbacks, and the second train went over a small mountain. …How far apart are they now?
IF you mean “as the crow flies” …Who knows. No way to tell.
2nd assumption, that there’s a track to connect them along that hypotenuse.. which there probably isn’t.
The only safe way to answer the question is to say that if you follow the tracks you know are between them, the ones they traveled to get where they are. .They’re the same 45 miles apart no matter which way they went. .
Unless they both went the same direction on the same track.
