Hi,

A passenger train leaves Chicago while a freight train leaves from New York headed toward each other on parallel train tracks.

the cities are 560 miles apart

freight train is traveling 20 mph slower than a passenger train's ratehighlight%28x%29 

Question states*** They meet in 4 hours.  Note D = rt

 4x + 4(x-20) = 560mi

   8x = 640

    x = 80mph, rate of the passenger train.  Freight Train's rate is 60mph

and...

  4hr%2A80mph+%2B+4hr%2A60mph+=+560mi
