Question 285609: if one train left point A at 60 miles an hour, and another train left point B going 100 miles an hour and the distance between the two points was 50 miles when would they cross paths? (and of course they are moving towards each other)

You can put this solution on YOUR website!
You can just add their speeds in 1 equation
d+=+r%2At
50+=+%28100+%2B+60%29%2At
t+=+50%2F160
t+=+5%2F16 hrs
t+=+%285%2F16%29%2A60 min
t+=+18.75 min
The cross paths in 18 min and 45 sec
