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

(1 point)
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.

Answer 1

Europe: max 111, min 74, range = 111 − 74 = 37 mph.
North America: max 128, min 85, range = 128 − 85 = 43 mph.

So Europe = 37 mph; North America = 43 mph.
