5 In this question, i is a unit vector due east, and j is a unit vector due north.
A plane flies from P to Q where
?
PQ = (960i + 400j) km. A constant wind is blowing with velocity
(–60i + 60j) km h–1. Given that the plane takes 4 hours to travel from P to Q, find
(i) the velocity, in still air, of the plane, giving your answer in the form (ai + bj) km h–1, [4]
(ii) the bearing, to the nearest degree, on which the plane must be directed. [2]

here!!!
thi is not what i had t ask!!
but at the momnet igot this!!
i amseraching my pc for that question!!
