A model airplane competition has the following rules: Each plane must fly to a point 1 km from the start and then back again. The point km winner is the plane with the shortest round-trip time. The contestants are free to launch their planes in any direction, so long as the plane travels exactly 1 km out and then returns. On the day of the race, a steady wind blows from the north at 8.5 m/s. Your plane can maintain...

Background: Jerome and Paul are competitive brothers. They live on a small farm on the northern bank of a river that runs purely east and west and that flows to the east at a rate of 1.400 m/s . The brothers have run some time trials on the farm pond, and they know that, in still water, Jerome can paddle the family canoe at a steady rate of 2.950 m/s for a considerable length of time. When younger brother Paul runs a...
