Answer:
The trains will meet after 2.6 hours.
Step-by-step explanation:
Add up the distances traveled by the two trains:
distance1 = (100 mph)(t hours)
distance2 = (90 mph)(t hours)
Sum of distance1 and distance2 = 494 miles = (190 mph)(t hours)
Solving for t, we get t = 494 miles / 190 mph = 2.6 hours
