Two friends decide to get together; so they start riding bikes towards each other. They plan to meet halfway. Each is riding at 6 MPH. They live 36 miles apart. One of them has a pet carrier pigeon and it starts flying the instant the friends start traveling. The pigeon flies back and forth at 18 MPH between the 2 friends until the friends meet. How far does the pigeon travel?

Open Calculator

Answer

It takes 3 hours for the friends to meet; so the pigeon flies for 3 hours at 18 MPH=54 miles.

There's a legend that physicist von Neumann was given this problem and within seconds provided the correct answer. The person giving the problem said, "It's funny how most people use an infinite series when there is a much simpler way." Von Neumann responden, "There's a simpler way?"
