∙ 11y agoEven though Tyrannosaurus rex is a large animal, the legs of a Tyrannosaurus are proportionally different to those of say another large animal, the elephant.
Elephants can reach about 15 miles per hour (mph). An elephant has short metatarsals and short toes. They can't trot or gallop. Tyrannosaurus, on the other hand, has feet similar to those of birds with long toes and metatarsals that were probably more mobile. These traits are often found to be characteristic of runners in modern animal's.
So, how fast can a ~6 ton animal with running legs actually go? Or could they even run?
One thing that there is agreement is that the amount of an animals total mass that is dedicated to leg muscle is important to it's potential speed. This is difficult to estimate as no T.rex leg muscles are known and estimating the mass of extinct creatures is difficult.
Some palaeontologists have suggested that T.rex could probably reach about 30-45 mph. This is based on research into scaling trends in modern day animals. It suggests that so long as an animal maintains the a similar percentage of leg muscle and a similar limb design then it can maintain speed it grows.
In more recent years there has been an increase in researchers trying to simulate animal locomotion in an attempt to better understand it. There is research that creates virtual dinosaurs and applies an "evolutionary algorithm". The virtual dinosaurs learn how to run and then try and cover as much distance in a given amount of time. They call this technique "evolutionary robotics".
One of these studies estimated that an adult T.rex could attain nearly 18 mph, assuming that about 25% of the total animal's mass was leg muscle. However changing the assumptions about the speed at which the muscle can twitch and the total amount of muscle in each leg can increase or decrease the speed. They also think the results are conservative because the simulation doesn't factor in elastic tissues that might increase speed. Other mathematical modeling has suggested speeds of about 11 to 25 mph. This study follows research that suggests that there is a decrease in 'athletic prowess' as an animal grows.
There are also debates about whether the skeleton (especially the femur) could withstand the impact forces of running.

How fast does the t-rex motorcycle goes?
As fast as T-Rex could run.
Was Tyrannosaurus Rex a terrifying predator or a lumbering scavenger?
Tyrannosaurus Rex was to slow and heavy to run and its arms were tiny to grab things. It also had bad eyesight and a good sense of smell. All of this suggests that Tyrannosaurus Rex was a scavenger.
How does a Tyrannosaurus Rex's tail helped its balance?
The tail of a T. rex primarily served to balance the weight of the rest of its body and its massive head. Contrary to its depiction in Jurassic Park T. rex probably could not run fast.
Why did the tyrannosaurus run so fast?
It enjoyed lunch on the hoof. Most of it's prey could run fast so it had to run faster to be able to eat.
How much fast tyrannosaurus run?
21 miles
Who would win in a fight a raptor or t-rex?
The largest type of raptor was Utahraptor. It was 23 feet long and weighed 1,000 lb. However, even Utahraptor would be no match for Tyrannosaurus, which was 40 feet long and weighed in at 6 to 12 tons. If it wanted to survive the encounter it would have to run away from the Tyrannosaurus as fast as it could.
How did the T-Rex run?
Tyrannosaurus rex was not capable of lifting both feet off the ground at once. However, some scientists say that they could still reach speeds up to 40 miles per hour.
What eat's t-rex?
anything eating meat. sometimes they would die and be eaten by scavengers or attacked by other t rexes or even stronger predators.
What is the giganotosaurus speed?
Some experts agree that it could run at about 15-25 mph (just about as fast as a t rex). But I think both of those dinosaurs could maybe run 30 mph.
Who would win a fight- a croc or T. rex?
No modern crocodile would be able to beat an adult Tyrannosaurus rex in a battle, but it could escape to the water. A large crocodile, however, could kill a very young Tyrannosaurus. Some prehistoric crocodile species, such as Deinosuchus or Sarchosuchus, were far larger than any modern species, growing up to 40 feet long. These didn't live at the same time as Tyrannosaurus, but if an adult of one of these species came across a T-rex, they would have been relatively evenly matched at first. However, if the T-rex survived long enough, the crocodile would have run out of energy and been forced to retreat to the water. There is some fossil evidence that T-rex may have lived in packs, and if this is the case, a pack of T-rex would have had a huge advantage over any Deinosuchus attack.
How fast can a troodon run?
There is quite a bit of debate about this in the science community. The estimates on T. rex's top sped has been put at a low of about 17 mph to a high of 25 mph.
How fast can a mini rex rabbit run?
Most rabbits prefer to run in an open room.
