As for the second question: I could run to school in a second and save money on plane tickets by running to foreign countries and easily run.....anywhere. With speed-reading i can finish a hundred books in a day, learn a new language every day etc. The possibilities are endless. Honestly the only advantage Spidey's powers have over the Flash's is his Spider-stregnth and Webs for reaching things that far away. However i could just run towards what i want to reach.
