Question

a planet rotates on its axis through its poles and 1 revolution takes 1 day (1 day is 18hours). The distance from the axis to a location on the planet 30 degrees north latitude is about 2296.5 miles Therefore a location on the planet at 30 degrees north latitude is spinning on a circle with a radius of 2296.5 miles compute the linear speed on the surface of the planet at 30 degrees north latitude

Answer 1

circumference = 2*pi*radius
that's how far you go in 18 hours
speed = distance/time
