1a. Suppose at one point along the Nile River a ferryboat must travel straight across a 1.40-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.01 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 18.6 mph in still water. In what direction should the ferry captain direct the boat so as to travel directly across the river? ___________degrees south of east
1b. Suppose at one point along the Nile River a ferryboat must travel straight across a 1.01-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.04 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 22.7 mph in still water. If the captain points the boat directly at the target location on the east bank of the river, how far downstream will she be from the target when she lands on the east bank?
