Two cars start driving toward each other from towns 300 miles apart. Car A travels at 60 mph, and Car B travels at 40 mph. At the exact same moment Car A starts, a remarkably fast falcon flies from Car A's roof toward Car B at 100 mph. When the falcon reaches Car B, it immediately turns around and flies back to Car A, repeating this until the cars crash. What total distance does the falcon fly?
300 miles
The cars travel toward each other at a combined speed of 60 + 40 = 100 mph. The distance is 300 miles, so they crash in exactly 3 hours (300 / 100). The falcon flies continuously for those same 3 hours at 100 mph. 3 hours * 100 mph = 300 miles.
