Question 873619
An eastbound train averaging 60 miles per hour and a westbound train averaging 50 miles per hour depart from different cities at the same time heading toward each other on parallel tracks.
 
If they pass each other 3 hours after they departed, what is the distance between the two cities?
.
applying the distance formula of d=rt
"distance traveled by eastbound" + "distance traveled by westbound"
3(60) + 3(50)
180 + 150
330 miles (distance between the two cities)
