Jerome and Paul are competitive brothers. They live on a small farm on the northern bank a river that runs purely east and west and that flows to the East at a rate of VR.

The brothers like to visit their Uncle Leo who lives on the southern bank of the river. The river is wideat this point, of known width , and their uncle's dock is a known distance to the east of the pointwhich is directly across the river from the brothers' house. Paul is not nearly as strong a paddler as isJerome, but paddling together they can maintain a known paddling speed in the farm pond. Jeromeknows that if they point their canoe due south, they will always end up to the east of Uncle Leo's dockby the time they have paddled across the river. He wants to know in which direction they should head to arrive exactly at Uncle Leo's dock without any wasted effort.
