Spiderman doesn't have superhuman speed. He has the agility and reflexes. Superhuman speed is something like the Flash.
You need to tell that to wikipedia then.
Powers, skills, and equipment A bite from a radioactive spider triggers mutations in Peter Parker's body, granting him superpowers.[86] In the original Lee-Ditko stories, Spider-Man has the ability to cling to walls, superhuman strength, a sixth sense ("spider-sense") that alerts him to danger, perfect balance and equilibrium, as well as superhuman speed and agility.[86] The character was originally conceived by Stan Lee and Steve Ditko as intellectually gifted, but later writers have depicted his intellect at genius level.[87] Academically brilliant, Parker has expertise in the fields of applied science, chemistry, physics, biology, engineering, mathematics, and mechanics. With his talents, he sews his own costume to conceal his identity, and he constructs many devices that complement his powers, most notably mechanical web-shooters to help navigate and trap his enemies along with a spider-signal as an flashlight and a warning beacon to criminals.[86]
