Two boats on opposite banks of a river start moving towards each other. they first pass each other 1400 meters from one bank. they each continue to the opposite bank, immediately turn around and start back to the other bank. when they pass each other a second time, they are 600 meters from the other bank. we assume that each boat travels at a constant speed all along the journey. find the width of the river?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
