Earth rotates on an axis through its poles. The distance from the axis to a location on Earth 30º north latitude is about 3429.5 miles. Therefore, a location on Earth at 30º north latitude is spinning on a circle of radius 3429.5 miles. Compute the linear speed on the surface of Earth at 40º north latitude.

The art class is planning to paint a mural on an outside wall. this figure is a scale drawing of the wall. width: 11 in length: 28 in unit rate: 1.5 ft per in. write the ratio of the area of the drawing to the area of the actual mural. write your answer as a unit rate. show that this unit rate is equal to the square of the unit rate 1.5 ft per in
