Question

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 helicopter’s 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
C28.47° latitude and -7.35° longitude
D38.34° latitude and 220.95° longitude
E-38.34° latitude and 220.95° longitude

Answer 1

The answer would be C.)28.47 lat -7.35 long

Answer 2

Answer:

Option A - 28.47° latitude and 7.35° longitude      

Step-by-step explanation:  

Given : 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°.

To find : What is the helicopter’s net change in latitude and longitude as it travels from Hong Kong to Jakarta?    

Solution :

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°.

The net change in latitude as it travels from Hong Kong to Jakarta is given by subtracting the latitude from Hong Kong to Jakarta.

i.e. $N_l=22.27^\circ-(-6.20^\circ)$

$N_l=22.27^\circ+6.20^\circ$

$N_l=28.47^\circ$

The net change in longitude as it travels from Hong Kong to Jakarta is given by subtracting the  longitude from Hong Kong to Jakarta.

i.e. $N_l=114.15^\circ-(106.80^\circ)$

$N_l=114.15^\circ-106.80^\circ$

$N_l=7.35^\circ$

Therefore, The net change from Hong Kong to Jakarta is 28.47° latitude and 7.35° longitude.

So, Option A is correct.
