As Fast as a Rabbit
Rabbits are very swift animals due to their long hind legs.
A person may be known to be fast as a rabbit if they are swift. The long
back legs of a rabbit allow them to quickly escape possible predators Jack Rabbits are very powerful jumpers and are known
to be fast runners. They can reach speeds of up to 45 miles per hour. Cottontail rabbits are also quick. They tend to scurry away
from predators and hide rather than race away from the scene like the jack rabbit. The
cottontail rabbit can achieve speeds of 35 miles per hour. That is why when people
are very fast, we sometimes compare their speed to that of a rabbit.
