v=√2.5r
The equation describes the relationship between the radius r in feet of an unbanked curve and the maximum velocity v in miles per hour that a car can safely go around the curve. A primary road with a speed limit of 35 miles per hour curves through a residential area. What is the radius of the unbanked curve?

a) 490 ft
b) 14 ft
c) 49 ft
d) 450 ft

The max speed is 35 miles/hr and and v= sqrt(2.5)r describnes the radius and speed relationship so you calculate r first but it will be in miles so convert to get it in feets
