If an ATV is moving at 55 mph, then its speed is 55 mph. Both the original speed and the converted speed are the same.
The speed of a 212cc engine depends on various factors such as the vehicle it is powering, gearing, weight, and aerodynamics. However, in general, a 212cc engine can reach speeds of around 40-50 mph in a go-kart or similar small vehicle.
Apollo Ohno has been recorded reaching speeds up to approximately 36-37 mph (58-60 km/h) while speed skating.
Jackie Robinson was known for his speed on the baseball field and was estimated to be able to run the 100-yard dash in 10 seconds. This would equate to a speed of approximately 18 miles per hour (mph).
Oh, dude, 20cc is a unit of volume, not speed. It's like asking how tall a liter is in inches. If you're talking about a vehicle, you'd need more info like engine size, gear ratio, tire size, and a bunch of other stuff that makes my brain hurt just thinking about it. So, yeah, 20cc doesn't really translate to mph.
about 90 mph
Speed
Can't answer that one, to many variables.
The top speed of the honda engine is about 35- 40 mph mongolos
Saturn ION 2.2 L ecotec engine has a top speed of 78.6 mph which is fairly fast.

Well, my Kawasaki EN450 goes fast enough to scare me...and I'm fearless. It can get up to 90+ mph. The top speed depends on how the bike is geared, how well it cuts the wind and how much weight it is carrying so, there is no really good answer.
"43cc" is not a speed - sounds like the size of a small engine, but size does NOT define it's speed or horsepower.
fast as a car speed
69 mph It can be any speed but probably about 60 mph
They measure engine speed in RPM, but car speed in MPH. If you want to know how they know how fast the cars go from the stands or the officials' booths, that is what radar guns are for. Inside the cars, the speedometer tells how fast they are going, and the tachometer tells how fast the engine is running.
The speed of a 12hp engine in mph depends on various factors such as the weight of the vehicle, the gear ratio, and the aerodynamics. Generally, a 12hp engine can propel a small vehicle like a go-kart or a lawnmower to speeds ranging from 20-40 mph. However, for a more accurate estimation, a specific vehicle and its characteristics would need to be considered.
