Solve the problem.
-The Earth rotates about its pole once every 24 hours. The distance from the pole to a location on Earth 35° north latitude is about 3,243.8 miles. Therefore, a location on Earth at 35° north latitude is spinning on a circle of
Radius 3,243.8 miles. Compute the linear speed on the surface of the Earth at 35° north latitude.
A) 135 mph
B) 20,381 mph
C) 795 mph
D) 849 mph

Question

Quizplus · Accepted Answer

The circumference of the circle is 2πr = 2π(3,243.8) = 20,381 miles. The linear speed is the distance traveled divided by the time taken, which is 20,381 miles / 24 hours = 849 miles per hour.
