I suppose that was Cheetah's cruising speed. He's amazingly fast, be he does get tired. He's also not fast enough that your eyes couldn't track him either, since Knuckle and Murrel were able to during their fight.
It sucks that the ambush didn't work though. Shoot just had to slap the guy's legs and he'd seal away his speed. I really wanted to see his face when he goes bankrupt.
