The formula v=√2.3r v= L 2.3
r
models the maximum safe speed,
v
v
, in miles per hour, at which a car can travel on a curved road with radius of curvature
r
r
, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 330 feet. What is the maximum safe speed?

For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?)
