Explain how you could determine, given the following 3 pieces of information, (you need all 3 together not each one individually) the radius of the Earth.
1) Jakarta and Port Moresby, the capital of Paua New Guinea, are two cities on the equator.
2) A plane leaves from Port Moresby bound for Jakarta at a speed of 500 mi/hr and arrives there 5 hours later.
3) A student in Port Moresby turns on a baseball game that is being played in Jakarta and starts right at the time of sunset in Port Moresby. The game finishes 3 hours later (an extra inning affair). The announcer comments at the end of the game that the Sun is just setting in Jakarta.
