Question 1138656
.
<pre>

Let x be the difference of latitudes (the larger minus the smaller), in degrees.


Then


    {{{R*(x*(pi/180))}}} = 400,


where R is the Earth radius of 6378 kilometers.


It gives


    x = {{{(400*180)/(pi*R)}}} = {{{(400*180)/(3.14*6378)}}} = 3.595 degrees.   <U>ANSWER</U>  



<U>CHECK</U>.  Lynchburg, Virginia,latitude is           37.4138° N

        Myrtle Beach, South Carolina latitude is  33.6891° N

        The difference of latitudes is             3.725°
