Hi, Rachel.

The farthest place on earth from any point is the place exactly 
opposite it on the globe. Can you find the latitude and longitude of 
Atlanta? If so, then you can find the latitude and longitude of the 
opposite place. Then you can look up this place in an atlas or on a 

Here is how to find the latitude and longitude of this place. The 
latitude of Atlanta is some number of degrees NORTH of the equator. 
The latitude of the opposite place is that same number of degrees 
SOUTH of the equator.

The longitude takes a little more work. The longitude of Atlanta is 
some number of degrees WEST of the Greenwich meridian (the north-south 
line that passes through Greenwich, England). Take this number and 
SUBTRACT it from 180 degrees. The longitude of the place opposite 
Atlanta is this number of degrees EAST of Greenwich.
