At 29 degrees North (or South, for that matter) one degree of longitude is 97.439 km, or 60.548 miles, using the GRS1980 ellipsoid.

The distance between meridians of longitude on a sphere is a function of latitude.
Mathematical expression: length of a degree of longitude = cos (latitude) * 111.325 kilometers
So, cos 29 * 111.325 = 97.367 km
