Find the range of the speeds of the fastest steel roller coasters on both continents.

Europe: Range = 115 - 74 = 41 mph

North America: Range = 100 - 85 = 15 mph

To find the range of the speeds of the fastest steel roller coasters on both continents, we need to determine the highest and lowest speeds from the given data.

From the data given for Europe, the highest speed is 115 miles per hour (11|1), and the lowest speed is 75 miles per hour (7|4).

From the data given for North America, the highest speed is 128 miles per hour, and the lowest speed is 85 miles per hour.

To calculate the range, we subtract the lowest speed from the highest speed.

For Europe: Range = Highest Speed - Lowest Speed
Range = 115 mph - 75 mph
Range = 40 mph

For North America: Range = Highest Speed - Lowest Speed
Range = 128 mph - 85 mph
Range = 43 mph

Therefore, the range of the speeds of the fastest steel roller coasters on both continents is 40 mph in Europe and 43 mph in North America.
