At 0900 hours a ship sails from the point

with the position vector (2i+3j)km relative to an origin O. The ship sails north-east with a speed of

i) find in terms of i and j, the velocity of the ship.

ii) show that the ship will be at the point with position vector (24.5i+25.5j)km at 1030hours.

iii)find in terms of i,j and t, the position of the ship t hours after leaving P.
