Assume that the Earth is spherical and recall that latitudes range from 0 at the Equator to 90 N at the North Pole. Consider Dubuque, Iowa (42.50 N latitude), and Guatemala City (14.62 N latitude). The two cities lie on approximately the same longitude. Do not neglect the curvature of the Earth in determining the following.

If one could burrow through the Earth and dig a straight-line tunnel from Dubuque to Guatemala City, how long would the tunnel be?
