Solve the problem.
-The formula $\mathrm { v } = \sqrt { 2.5 \mathrm { r } }$ models the safe maximum speed, $\mathrm { v }$, in miles per hour, at which a car can travel on a curved road with radius of curvature, $r$, in feet. A highway crew measures the radius of curvature at an exit ramp as 360 feet. What is the maximum safe speed?
A) 30 mph
B) 36 mph
C) 27 mph
D) 35 mph
