Remember, you will be measuring distances between the North Rim and the Colorado River, and then the South Rim and the Colorado River to be able to calculate rates. Please calculate your answer in centimeters per century years (cm/century). Tiyo Point on the North Rim: 36.1806, -112.1278 & Colorado River between: 36.1055, -112.1562 & Hopi Point on the South Rim: 36.0733, -112.1551 Correct! The north side of the Colorado River (from Tiyo Point) is widening at a rate of about 18 cm/century. The south side of the Colorado River (from Hopi Point) is widening at a rate about 7cm/century. None of the answers listed are even close. Thus, this is the best answer. The north side of the Colorado...
