Find the linear speed in terms of MPH

Round to nearest integer as needed.

The planet Mars has a radius of 2000 miles and rotates one revolution every 25 hours. What is the linear speed of a point on its equator, in miles per hour? The linear speed is approximately miles per hour.

Solution

circumference of Mars at equator = 2r = 2*2000 = 4000 miles
linear speed of a point on the equator = 4000 mi/25hrs 502.65 mi/hr
