Edit: there is a problem with this calculation, and I had fixed it but I cant find the fixed calculation to put in the post. But I can remember the fixed calculation was not lower than 15,000.

So the Flash had to mail a letter to his Grandma Ester in Florida and to Arrow in Star City. Star City is Seattle.Star City is 600 miles away from Central Cty.

Florida is 3,132 miles from Seattle.

600+3132=3,732. Now he has to run back to central City.

3,733 +3,132= 6,864 miles. But no we have to subtract 600 since he's not heading back to Star City.

6,864-600=6,864 miles a second.

6,864 miles a second = mach 29624.53

This isn't accounting for the other 50 + guests since we don't know where they live.

@watcher5000:

Thank you very much for this. It made me laugh so hard

Flash has no Idea how fast he is. He can't cover a few feet in under a second and clocks like 4k MPH in his speed room but then he times lightning, opens time rifts and runs across the country in an instant.

just chalk it up to Barry being a Jobber and the old faithful...

@watcher5000: What is that supposed to mean?

@sanitrize1999: based on your distance numbers, and the average time i got on my stopwatch for the time Barry was out running (1.66333333 seconds), the minimum speed would be Mach 19,516. About 2% lightspeed

CW Flash is Mach "Not enough".

@webinyoureye11: That .663333 makes a big difference lol.

@sanitrize1999: just thought you were looking for an accurate number

@webinyoureye11: I wasnt being sarcastic. I really meant it made a big difference.It took off 10,000 mach.

Thanks for taking the time to help make an more accurate answer.

@sanitrize1999: no problem. I'm glad we got one semi quantifiable feat that puts Barry at a whole percent the speed of light definitively

It's a very accurate gif that is describing my feeling after reading this.

@watcher5000: You were sad about being proven wrong?

No, but if you want to tell yourself that then sure.

@watcher5000: I mean the proof is there.

If we take this seriously then CW flash would have to be dozens of times faster than what you calc'd to deliver invites to all the other guests in 2 seconds which is just crazy.

@watcher5000: I mean, we haven't gotten an exact measurement of his speed for a whole season. And the speed force said he reached the finish line, so he probably gotten even faster since it was the end of his journey. Since we know his speed was limitless in 2024. 4 years after he got his speed in the original timeline. So the time matches up, it's been 3-4 in the current timeline. Also it was said his emotions effect his speed, since he was really happy at that time, he could have gotten a boost from that.

@rubear: Lol. So true

@purpledeadragon: not gonna lie, I'd pay to see that.
