Two trains are 212 miles apart, and their speeds differ by 20 mph.
Find the speed of each train if they are traveling toward each other and will meet in 2 hours.
:
Let s = speed of the slower train
Let (s+20) = speed of the faster
:
Write a distance equation Dist = speed * time
:
slow train dist + fast train dist = 212 miles
2s + 2(s+20) = 212
2s + 2s + 40 = 212
4s = 212 - 40
s = 172/4
s = 43 mph
:
You can find the speed of the fast train. Check by finding the total distance
