Two points a and b on the same surface of the earth are on the same circle. If A has a latitude of 10 degrees and B has a latitude of 6.4 degrees south what is the distance between a and b assume that the radius of the earth is 3960 miles.

Langleyville (43 degrees S, 77.6 degrees w) and Cajun Country (25 degrees s, 77.5 degrees w) have almost the same longitude, which means that they are roughly due north-south of each other.  Set up all the work to find the approximate distance in miles between the cities assuming the radius of the earth is 4000 miles.

26. A map suggests that Atlanta is 730 miles in a direction of 5.00° north of east from Dallas. The same map shows that Chicago is 560 miles in a direction of 21.0° west of north from Atlanta. Modeling the Earth as flat, use this informa- tion to find the displacement from Dallas to Chicago.

You start off on a hike and walk 25km in a direction 30 degrees South of West followed by 30km to the North. What is the direction from your starting point to your destination?
