The GateKeeper is one of the tallest, fastest, longest wing roller coasters in the world. GateKeeper climbs a record 170 feet (tallest inversion of any roller coaster) and reaches a maximum speed of 67 mi/h (fastest of any non-launched wing coaster). The entire 4164-foot ride takes an unbelievable 2 minutes 20 seconds to complete. What is the average rate of speed for GateKeeper, in miles per hour? Express your answer to the nearest whole number.
