Question 1139147: The passenger train headed north at 70 miles per hour at 6 a.m. At 8 a.m. the freight train headed south from the same station at 30 miles per hour. At what time will the trains be 440 miles apart. Begin by drawing a diagram of distance traveled and writing the distance equation. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Distance is velocity* time
Passenger train travels x hours and 70x miles in that time.
The freight train travels x-2 hours and 30(x-2) miles in that time.
so 70x+30x-60=440
100x=500
x=5 hours
at 11 am, the passenger train has gone 350 miles and the freight train 90 miles
