If you graphed those equations after putting them into slope-intercept form, you would see that the slope of both the lines is 1.  Identical slopes tell us that the lines are parallel and that they will NEVER IN A BILLION TRILLION YEARS ever cross.  Therefore, there is no solution.  Second choice down.

V = rw

where; v = velocity , r = radius , w = angular speed

you're given the diameter = 0.5 miles so the radius = 0.25 miles

180 = (0.25)w
180/0.25 = w
720 radians per hour = w

2pi radians in 1 revolution

720 rad/hr * 1 rev / 2pi rad = 720/2pi rev/hr
= 114.6 rev/hr
