2) A horizontal curve on a two-lane (one lane in each direction) highway (12-ft lanes) has PC at station 127 80 and PT at station 134 00. The central angle is 47 degrees, the superelevation is 0.08, and 25.80 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
