Question 116945: A passenger train traveling due west at 40km/h passes a freight train traveling due east at 90km/h. How long after they pass each other will the trains be 325km apart?
My calculation is the distance travelled by both trains are 325 Km.
The time = x.
Therefore,
325 - 40x = 90x
x=2.5 or 2.5 hours, so after 2.5 hours they will be 325 km apart. Is this correct?
