To find: the distance between the city SF with latitude

Answer to Problem 62E
Approximately 686 miles
Explanation of Solution
Given:
Radius of earth is 4000 miles. And both cities are on same longitude.
First step is to convert the latitudes from
Now, find the difference in latitudes of the two cities.
Now, convert the degrees to radians.
Lastly, multiply the above radian with the radius of earth to find the arc length which corresponds to the distance between the two cities.
Conclusion:
The distance between the two cities is approximately 686 miles.
