The passenger train travels 400 miles in the same time it takes the freight train to travel 320 miles. Find the speed of each train.Answer by mial_ibanez22(3)   (Show Source): You can put this solution on YOUR website!let x=speed of the freight train 12+x=speed of the passenger train the speed is equal to distance/time and time is equal to distance/speed.. the time for the passenger train is equal to the time of the freight train.... simplifying,4(12+x)=5x x=48miles-->speed of the freight train 12+x=60miles-->speed of the passenger train ^^
