An aeroplane flies due North from a town T on the equator at a speed of 950km per hour for 4 hours to another town P. It then flies eastwards to town Q on longitude 65°E. If the longitude of T is 15°E, (a) represent this information in a diagram ; (b) calculate the : (i) latitude of P, correct to the nearest degree ; (ii) distance between P and Q, correct to four significant figures. [Take ; Radius of the earth = 6400km].
Explanation
(a) (b)(i) (to the nearest degree) (ii) Distance between P and Q, correct to four significant figures. Longitude difference = 65° - 15° = 50° Using, where = = (to 4 significant figures).
