These types of questions keep me from getting perfect first 3 pages:
07H-28: How far apart are Moscow(37 degrees 36'E) and Copenhagen(12 degrees 34'E) if both lie at 55 degrees 43'N latitude? Calculate the distance along a line of constant latitude.
Also, I do not get how to do this scaling problem:
07H-46: A creole recipe calls for 2 cups onion and feeds 8 people. How much onlion is needed to feed 95 people if each serving was cut down to 75% of the recipe amount?
