Two trains are moving towards each other, each traveling 75 mph. When the trains are 500 miles apart, a hawk starts flying back and forth between them (as soon as it gets to one train it turns around and flies back to the other). If the hawk can fly at a speed of 90 mph how far will the hawk have flown when the trains meet? Thanks.

Hi alikn; 500 / 150 * 90 = 300 miles the hawk flies.
