Question 17

A boat B B\,B moves with a constant velocity. At noon, B B\,B is at the point with position vector (2i−5j) km(2\mathbf{i} - 5\mathbf{j}) \text{ km}(2i−5j) km with respect to a fixed origin OOO. At 1430 the boat is at the point with position vector (−8i+10j) km(-8\mathbf{i} + 10\mathbf{j}) \text{ km}(−8i+10j) km.

a.
