Summer Thrill Rides

July 22, 2019
 

Over the summer millions of people around the world visit amusement parks. Previously heralded as the “World’s Largest Amusement Park,” Cedar Point Amusement Park in Sandusky, Ohio earned that title. At one time, Cedar Point had 72 rides, 16 of which are roller coasters. What percent of the Cedar Point’s rides are not roller coasters? Express your answer as a decimal to the nearest tenth.

 

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.

 

Since standing in line for rides can take up a great deal of time at some amusement parks, serious riders find it necessary to have a good plan of action to make the best use of time. Today Matt is interested in riding only roller coasters, but he has only enough time to ride 12 of the 16 roller coasters at Cedar Point. How many combinations of 12 roller coasters are there, assuming Matt doesn’t plan to ride any roller coaster multiple times today?
