The table shows the latitude and longitude of three cities.
Notice that the distance between each line of latitude is about the same. The distance from the equator to the North Pole is \frac{1}{4} of the circumference of Earth, and each degree of latitude is \frac{1}{90} of that distance. Estimate the distance between one pair of latitude lines in miles.
