Find the range of the speeds of the fastest steel roller coasters on both continents.
The range of the speeds of the fastest steel roller coasters in Europe is
mph.
The range of the speeds of the fastest steel roller coasters in North America is
mph.
Now are you sure both of the ranges are correct?
The range of the speeds of the fastest steel roller coasters in Europe is 47 mph (from 74 to 121).
The range of the speeds of the fastest steel roller coasters in North America is 35 mph (from 85 to 120).
Are you sure both of the ranges are correct?
I apologize for the mistake in my previous response. The corrected range for the fastest steel roller coasters in Europe is 47 mph (from 74 to 121), which is correct. However, I made an error in calculating the range for the fastest steel roller coasters in North America.
To find the range of the speeds of the fastest steel roller coasters in North America, we need to subtract the lowest speed from the highest speed. The lowest speed in the data set is 85 mph and the highest speed is 128 mph. Therefore, the range of the speeds of the fastest steel roller coasters in North America is 43 mph (128 - 85).
I apologize for any confusion caused by my previous response.
Yes, I am now sure that both ranges are correct. The range for the fastest steel roller coasters in Europe is 47 mph (from 74 to 121), and the range for the fastest steel roller coasters in North America is 43 mph (from 85 to 128).
The range of the speeds of the fastest steel roller coasters in Europe is 74 - 119 mph.
The range of the speeds of the fastest steel roller coasters in North America is 85 - 128 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 in each set of data.
For the speeds of the fastest roller coasters in Europe, the highest speed is 119 mph (from the stem "11" with the leaf "9"), and the lowest speed is 74 mph (from the stem "7" with the leaf "4"). Therefore, the range for Europe is 119 - 74 = 45 mph.
For the speeds of the fastest roller coasters in North America, the highest speed is 128 mph (from Canada), and the lowest speed is 85 mph (from Mexico). Therefore, the range for North America is 128 - 85 = 43 mph.
Hence, the range of the speeds of the fastest steel roller coasters on both continents are 45 mph for Europe and 43 mph for North America.
