There are no such thing as mermaids. They are make-believe beings just like vampires, fairies and Santa Claus.
Mermaids don't exist. So nobody knows their speed.
they can swim as far as 50 km an hour and faster than a cheetah
You will never become a mermaid. They are not real and are only in stories. Like to swim? Join a swim club.
