Question

The arctic tern is an amazing bird that migrates 22,000 miles from the north pole to the south pole every September (and back home every April). At dawn on a certain September day, one bird is flying due south past Lisbon, Portugal, a distance of 3,124 miles away from his Arctic home. He is flying at a constant velocity of 17 miles per hour. How far, in miles, will he be home from home at sunset, exactly 12 hours later?
