Two cities are 3500 miles apart. A plane leaves one of them, traveling towards the other at an average speed of 300 miles per hour. At the same time a plane leaves the other, traveling towards the first, at an average speed of 400 miles per hour. How long will it take them to meet?
If you multiply 400 by 5 it equals to 2000 miles and 300 by 5 is equal to 1500 miles and if you plus them together it is equal to 3500 miles so It would take 5 hours for them to reach each other
