Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 115 miles per hour. The westbound train travels at 95 miles per hour. How long will it take for the two trains to be 504 miles apart?

6 answers

the distance between the trains grows at 115+95 = 210 mi/hr

So, it will take 504/210 hours to get 504 miles apart.
2.4hrs
The answer is 2.4 hours
I have a really hard problem and I need help answering it.

Two trains are traveling opposite directions. One train is traveling at the speed of 90 mph. The second train is traveling at a speed of 95 mph. The two trains travel for 3 hours. How far apart are the two trains?
3 times 90 plus 3 times 95
4 hours
