13. Lincoln, Nebraska (40.8° N, 96.7° W) and Dallas, Texas (32.8° N, 96.7° W) have approximately the same longitude which means Lincoln is roughly due north of Dallas. Assume that Earth is roughly spherical with a radius of 3,960 miles. Use the difference in latitude to approximate the distance between the two cities. Round your answer to the nearer mile.
