What is the longest roller coaster in the United Kingdom and how does it compare to the longest roller coaster in Mexico?
Sure. Can you tell me about the top speed of each roller coaster?
Certainly. The Ultimate has a top speed of 50 miles per hour (80 kilometers per hour) and the Steel Coaster has a top speed of 53 miles per hour (85 kilometers per hour). So, the Steel Coaster is slightly faster than the Ultimate.
