Introduction

Gun Devil in about five minutes killed 1.2 million people. This happens in Chapter 13 btw.

We'll be getting its speed.

Calculation

There's a simple method but I actually want to use the slightly harder method since it's somewhat more accurate.

All of Japan was hit in 26 seconds.

Japan is over 3000 km.

3000 km / 26 s = 115.3846153846153846 km/s or 115384.61538461539021 m/s, Mach 336.3982955819690801 or Massively Hypersonic.

All of China was hit in 37 seconds.

China is 5250 km.

5250 km / 37 s = 141.8918918918918919 km/s or 141891.89189189189347 m/s, Mach 413.67898510755651387 or Massively Hypersonic.

All of Soviet Union was hit in 210 seconds.

Soviet Union is 10,900 km.

10900 km /210 s = 51.9047619047619048 km/s or 51904.761904761908227 m/s, Mach 151.32583645703181219 or Massively Hypersonic.

All of Mexico was hit in 2 seconds.

Mexico is 3,000 km.

3000 km / 2 s = 1500 km/s or 1500000 m/s, Mach 4373.177843 or Massively Hypersonic.

All of India was hit in 15 seconds.

India is 3214 km.

3,214 km / 15 s = 214.2666666666666667 km/s or 214266.66666666668607 m/s, Mach 624.68415937803695215 or Massively Hypersonic.

All of the United States was hit in 124 seconds.

United States is noted to be 4,662 km.

4,662 km / 124 s = 37.5967741935483871 km/s or 37596.774193548386393 m/s, Mach 109.61158657011191053 or Massively Hypersonic.

All of Canada was hit in 7 seconds.

Canada is 7,560 km.

7,560 km / 7 s = 1080 km/s or 1080000 m/s, Mach 3148.688047 or Massively Hypersonic.

All of Hawaii was hit in 0.4 seconds.

Hawaii is 2,450 km.

2,450 km / 0.4 s = 6125 km/s or 6125000 m/s, Mach 17857.14286 or Massively Hypersonic.

The final one was noted he did it in about 5 minutes, so he went around the entire Earth in 5 minutes.

The Earth is 40,075 km.

40,075 km / 300 s = 133.5833333333333333 km/s or 133583.33333333334303 m/s, Mach 389.45578231292518012 or Massively Hypersonic.
