# Latitude and longitude

A helicopter is flying from Hong Kong to Jakarta. The latitude of Jakarta is -6.20, and its longitude is 106.80. The latitude of Hong Kong is 22.27, and its longitude is 114.15. What is the helicopters net change in latitude and longitude as it travels from Hong Kong to Jakarta?

Correct result:

x =  28.47 °
y =  7.35 °

#### Solution:

$y=\mathrm{\mid }{y}_{1}-{y}_{0}\mathrm{\mid }=\mathrm{\mid }114.15-106.8\mathrm{\mid }=\frac{147}{20}={\frac{147}{20}}^{\circ }=7.3{5}^{\circ }={7}^{\circ }2{1}^{\mathrm{\prime }}$
