You can put this solution on YOUR website! Let A = Speed of Train #1
Let B = Speed of Train #2
Equation 1: (One train is 15mph faster than the other)
Eqauation 2:
--------------------------------

Eqauation 2:
Multiply the 5 through.
Add 5B to both sides
Subtract 75 from both sides
Divide both sides by 10
Now plug 32.5 into equation 1 for B
Equation 1:
