speed = distance/time, so
2π*3960mi/24hr = ? mi/hr
2πrad/24hr = ? rad/hr
You are standing on the equator of the earth (radius 3960 miles).
a) what is your linear speed in miles per hour?
b) what is the angular speed in radians per hour?

2π x 3960 mi/24 hrs = 1036.73
mi/hrs
w=v/r= 1036.73 mi/hrs / 3960 mi
w = 0.262 rad/hrs
mi/hrs
w=v/r= 1036.73 mi/hrs / 3960 mi
w = 0.262 rad/hrs
