Question 152792: I am having problems with problem because of the different start times. The only problems online I have found with different start times are when the two vehicles are leaving from the same location.
At noon a train leaves Bridgton heading east at 90 mi/hr to Cogsville, 450 miles away. At 12:15 pm a train leaves Cogsville heading west to Bridgton at 100 mi/hr. At what time will they pass each other?

What I needed to do to start this problem finally hit me.
1. You need to figure how far Train A travels in 15 minutes. We use this to determine the distance between the two trains when Train B leaves its station at 12:15.
2. If 90/4=22.5 then 450-22.5=427.5 miles (This is the distance between Train A and Train B at 12:15
3. Now you just plug your numbers into the d=rt formula
450 - 22.5 = 90t + 100t
427.5 = 190t
2.25 = t
So the time traveled after the 12:15 start time is 2h 15m
Therefore the time that the trains pass each other will be 2:30 PM
