Answer:
a) A second of latitude has a length of 101.3 feet.
b) One degree of latitude has a length of 364800 feet.
Explanation:
These problems can be solved by rules of three.
a. One minute of latitude equals 6080 feet, what is the length of one second of latitude?
Each minute has 60 seconds. So, 60 seconds have 6080 feet. How many feet is there in 1 second?
1 second - x feet
60 seconds - 6080 feet
[tex]60x = 6080[/tex]
[tex]x = \frac{6080}{60}[/tex]
[tex]x = 101.3[/tex]
A second of latitude has a length of 101.3 feet.
b. What is the length of one degree of latitude?
Each degree of latitude has 60 minutes of latitude. One minute of latitude has 6080 feet. How many feet are there in 60 minutes?
1 minute - 6080 feet
60 minutes - x feet
[tex]x = 6080(60)[/tex]
[tex]x = 364800[/tex]
One degree of latitude has a length of 364800 feet.
