Question

select the correct answer
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?
a. -28.47° latitude and 7.35° longitude
b. -28.47° latitude and -7.35° longitude
c. 28.47° latitude and -7.35° longitude
d. 38.34° latitude and 220.95° longitude
e. -38.34° latitude and 220.95° longitude

Explanation:

Step1: Calculate the change in latitude

The latitude of Hong Kong is \(22.27^{\circ}\), and the latitude of Jakarta is \(-6.20^{\circ}\).
The change in latitude \(\Delta\varphi= - 6.20 - 22.27=-28.47^{\circ}\)

Step2: Calculate the change in longitude

The longitude of Hong Kong is \(114.15^{\circ}\), and the longitude of Jakarta is \(106.80^{\circ}\)
The change in longitude \(\Delta\lambda=106.80 - 114.15=-7.35^{\circ}\)

Answer:

B. \(-28.47^{\circ}\) latitude and \(-7.35^{\circ}\) longitude
