Hi Troy. Great question, let's see if I can help out. Using Longitude and Latitude we get a location on a sphere. It does this by describing two angles. One angle from the equator and a second angle from the prime meridian. This means if your location is described in a decimal format, then you can change both angles to degrees. We can also use the words west, east, north, or south to help us determine which way the angle is going, although some like to use negative sings to determine this. Example: London is located at 51.5074 degrees N and 0.1278 degrees W Converted: London is located at 51 degrees, 30 minutes, 27 seconds North, and 0 degrees, 7 minutes, 40 seconds West (rounded) Or using negatives: London is located at 51 degrees, 30 minutes, 27 seconds, and negative 0 degrees, 7 minutes, 40 seconds Hopefully that helps out. :^D

+yourfriendthemoose Your textbook answer key might be using the cheats for this. Try dividing the seconds by 60, then adding the minutes, and divide by 60 again, then add to the degrees. This is a "trick" that works most of the time, but because of rounding errors, isn't as accurate as the method described in this video.
