[GENERAL] Does it take super speed heroes/villains the same time it normally would to run around the world just they’re moving too fast relative to earths time they reach their destination “fast” according to earth time? or are they actually fast and feel like they reach there destination fast?

clarification: let’s say flash runs around the world- does it take him hours to get there relative to his perspective but fast to normal people because we can’t see him moving faster than tome? or does he run around the world in his point of view just as fast as a normal person sees him do it?

I get what you’re asking. It always depends on the person. 

Most iterations of Quicksilver experience each moment, so if he spends an hour at super speed while everyone is standing still as he runs, to him, he experiences that hour. He doesn’t tire and processes things but if he spends an hour running in his perception at what feels like 30mph down the highway, as all the cars and the world appear frozen, he experiences in “real time” every one of those sixty minutes. 

The Flash(es) with very few exceptions always control their perception. So Flash can make the same run and it feels like Quicksilver, OR to his POV it’s like he teleports... but Flash emphatically DOES see and experiences it all, just.... very differently, as the powers of the Flash are very cosmic and metaphysical. If the Flash also sees something during such a “quick jump” that he wants to interact with, he has absolute automatic control to “change modes”.
