Drivers must slow down from 65 miles per hour to 55 miles per hour to negotiate a severe curve on a rural highway.  A warning sign for the curve is clearly visible for a distance of 110 feet.  How far in advance of the curve must the sign be located in order to ensure that vehicles have sufficient distance to safely decelerate?  Use the standard reaction time (2.5s) and deceleration rate (11.2 ft/s^2) recommended by AASHTO for basic braking maneuvers.
