You can put this solution on YOUR website! 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
