Omni-Man's "Massively Hypersonic" speed explained
Omni-Man speed calculation:
Introduction
In season 1, episode 5, of the Invincible series, Debbie Grayson asked Nolan Grayson (Omni-Man) to get food from Rome and wine from Provence (https://www.youtube.com/watch?v=hN8mFZ6C3cU&t=15s).
Calculation
According to the episode, he should have been able to travel a distance of 4448 miles in 5 minutes (But it took him 20 minutes to return because of the shopping)
4448 miles ………….. 5 minutes
X miles ………….. 60 minutes (1 hour)
X= 266880/5= 53376 miles
So he could travel 53376 miles in an hour
Conclusion
Omni-Man speed (at least)= 53376 mph (Massively Hypersonic)
