Find the distance between this pair of points o... - SS3 Mathematics Longitude and Latitude Question
Find the distance between this pair of points on the earth surface: \(A(43{^\circ}N,\ \ 50{^\circ}E)\) and \(B(17{^\circ}S,\ 50{^\circ}E)\). Take \(R = 6,400km\)
A
6,550km
B
3,748km
C
3,412.90km
D
6,704.76
correct option: d
\[Angular\ difference\ = \ 43{^\circ} + 17{^\circ} = 60{^\circ}\]
\[Distance\ between\ the\ points = \frac{\theta}{360} \times 2\pi R\]
\(Distance\ between\ the\ points = \frac{60}{360} \times \frac{2}{1} \times \frac{22}{7} \times \frac{6400}{1} = 6,704.76\ km\)
