Question 25

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

Find the velocity of $B$ .

[3]

Find the bearing of the velocity vector

[2]

Find an expression, in terms of $t$ , for the position of $B$ $t\,$ hours after noon.
