Quizplus · Accepted Answer

The first plane travels for 0.5 hours before the second plane departs, covering 215 miles (430 mph * 0.5 hours). When both planes are in the air, they are 635 miles apart (850 - 215). The planes approach each other at a combined speed of 930 mph (430 mph + 500 mph). They meet after 635/930 hours, which is approximately 0.683 hours. In this time, the second plane travels 341 miles (500 mph * 0.683 hours) from Denver.
