Find the distance between the two cities San Francisco, California and Seattle, Washington.
Answer to Problem 106E
Explanation of Solution
Given:
The Latitude of San Francisco, California
The radius of Earth is 4000 miles.
Concept Used:
Formally, the number being subtracted is known as the subtrahend, while the number it is subtracted from is the minuend. The result is the difference.
We can write: minuend - subtrahend = difference.
For subtraction we can use the formulas:
Radian: The radian measure,
|
Calculation:
Step 1: Find the difference of Latitude between the two cities.
In this Problem Minuend (the first angle) has 37 minutes and 18 seconds whereas the 2nd angle has 47 minutes and 36 seconds.
We can rewrite the first angle in
We know that Difference::
Step 2: Now convert the angle
We know that:
Now the distance between two cities:
Distance:
Thus, the two cities San Francisco, California and Seattle, Washington is
