How do you figure out how many miles are between two parallels that are 1 degree apart?

To determine the distance between two parallels that are 1 degree apart, you can use the formula: distance = 69 miles × degrees of latitude. Since 1 degree of latitude is approximately equal to 69 miles, the distance between two parallels that are 1 degree apart is roughly 69 miles. This approximation varies slightly with latitude for lines of longitude, but it holds true for lines of latitude.
