How does martin luther king, jr. use hyperbole in his "letter from birmingham jail" ? ?

Martin Luther King Jr. used hyperbole in his "Letter From Birmingham Jail" with the statement "The nations of Asia and Africa are moving with jet like speed towards gaining political independence, but we still creep at horse and buggy pace toward gaining a cup of coffee at a lunch counter." A hyperbole is when someone used exaggeration for effect. 

Is this a joke question or what, obviously that means red dead redemption 2!
