It varies.
Each revolution rolls the truck ahead 1 tire-circumference.(2 revs per second) x (2.5 meters per rev) = 5 meters per second

4.5 meters in 9 second how fast in kilometer per hour?
250 feet per second = 170.45 mph
300 feet per second = 204.54 mph
Sloths move at 2 m.p.h.
Sloths are known to move very slowly, typically at a speed of about 0.03 miles per hour (0.05 km/h) when on the ground. They are adapted to a slow-paced lifestyle, as their slow metabolism and energy efficiency help them conserve energy.
80 times per second
250kilometers per second
Gravitational waves move at the speed of light in space, which is about 186,282 miles per second.
Gamma rays are electromagnetic waves, therefore they move at the speed of light.
41 metres per second
In a vacuum, the speed of light is 299,792,458 meters per second, which is roughly 300,000 km/second or 186,000 miles/second.
Two-toed sloths are known for their slow movement, typically traveling at a pace of about 0.24 kilometers per hour (approximately 0.15 miles per hour) when on the ground. In trees, they can move slightly faster, but they still maintain a lethargic pace, relying on their slow metabolism and energy conservation. Their deliberate movements are an adaptation to their low-energy diet of leaves.
about 11 kilometers per second
Very slow if it is 95.333 nanometres per second, fast if it is 95.333 kilometres per second.
Euglena move fast and amoeba move slower than Euglena
