t is time for freight train.
d is distance of the trip.

_______________rate__________time___________distance
Passenger______55____________t-3_____________d=55(t-3)
Freight________40____________t_______________d=40t

55*t=40*(t+3)
55*t=40*t+120
55*t=40*t+120
-120=40+55*t
-120=-15*t
(-120)/(-15);=t
t=8 hours
t+3=11 hours
distance =55*8=440 miles
distance =40*11=440 miles
