You can put this solution on YOUR website!
What distance are you using from NYC to LA?
I'll use 2800 and you can adjust if you need.
Rate*Time=Distance
85%2AT=D%5B1%5D
105%2AT=D%5B2%5D
D%5B1%5D%2BD%5B2%5D=2800
Substituting,
85T%2B105T=2800
185T=2800
T=15.13 hrs
So then in 15.13 hrs, the train from NY has traveled,
105%2A15.13=1589 miles
So they meet 1589 miles from NYC or 1211 (2800-1589) miles from LA.
