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 travelling. The pigeon flies back and forth at 18 mph between the 2 friends until the friends meet. How far does the pigeon travel?
Answer
It takes 3 hours for the friends to meet; so the pigeon flies for 3 hours at 18 mph=54 miles.
