Question 1067645: Two cities are 3500
miles apart. A plane leaves one of them, traveling towards the other at an average speed of 320
miles per hour. At the same time a plane leaves the other, traveling towards the first, at an average speed of 380
miles per hour. How long will it take them to meet?

Since they are travelling toward each other, their relative speed is 320 + 380 mph = 700 mph. The distance traveled is 3500 miles. Since t = d/v, we have t = 3500/700 = 5 hours
Ans: 5 hours
