8.–/6.25 points my notes question part points submissions used 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 2.35 m/s. the ferryboat has a motor that can move the boat forward at a constant speed of 21.8 mph in still water. in what direction should the ferry captain direct the boat so as to travel directly across the river?
