The range of the speeds of the fastest steel roller coasters in Europe is 47 mph and the range of the speeds of the fastest steel roller coasters in North America is 45 mph.
To find the range of the speeds of the fastest steel roller coasters in both Europe and North America, we need to determine the minimum and maximum speeds in each dataset.
For the speeds of the fastest steel roller coasters in Europe, the minimum speed is 74 mph (extracted from the stem-and-leaf plot). The maximum speed is 111 mph, which can be obtained by identifying the largest leaf in the plot (9).
For the speeds of the fastest steel roller coasters in North America, we need to find the minimum and maximum speeds for each country before calculating the overall range.
In Canada, the minimum speed is 90 mph, and the maximum speed is 128 mph.
In the U.S., the minimum speed is 93 mph, and the maximum speed is 120 mph.
In Mexico, the minimum speed is 85 mph, and the maximum speed is 95 mph.
Now, we can calculate the overall range by considering the minimum and maximum speeds from both continents.
For Europe, the range is 111 mph - 74 mph = 37 mph.
For North America, the range is the difference between the highest maximum speed (128 mph) and the lowest minimum speed (85 mph), which is 128 mph - 85 mph = 43 mph.
Therefore, the range of the speeds of the fastest steel roller coasters in Europe is 37 mph, and the range of the speeds in North America is 43 mph.
