Question 705289: two cars, 243 miles apart, begin driving towards each other on a long straight road. If one car is going 43mph, and the other is traveling at 38mph. At the same time a bird, starting on one car, fliea back and forth between the two cars as they approach each other. If the bird always flies at 52mph and turns around instantly at each car, how far has the bird flown when the cars collide? Answer by solver91311(24713) (Show Source):
The two cars start out 243 miles apart. They approach each other at 38 plus 43 = 81 miles per hour. Therefore they will collide in exactly 243/81 = 3 hours. If the bird travels at a constant 52 miles per hour for 3 hours, how far does he fly?
