Imagine that you set your watch at local noon in Kansas City on Monday and then fly to the Coast on Tuesday. You stick a pole into the ground on a sunny day at the beach, wait until its shadow is shortest, and look at your watch. The watch says 10:00 am. Are you on the East Coast or West Coast? What is the difference in Longitude? (hint: 360 degrees divided by 24 hours is 15 degrees. the sun moves through the sky at a rate of 15 degrees per hour)
