In One-Punch Man, a Saitama in training saves Tareo and his pet from a car that was very close to run over them. I'll be calculating his speed.
First, I need to find the distance between Saitama and Tareo, because that is the distance that Saitama ran to save him.
Saitama = 175 cm or 1.75 m
Panel height = 5.99 m
Distance = 1.75*5.99/[1.75*2tan(70/2)] = 4.27 m
After that, I need to find the length Tareo's head.
Garou = 177 cm
Tareo's head = 21.59 cm
Then, I need to measure the distance between Tareo and the car.
License plate = 140 mm or 0.14 m
Panel height = 1.45 m
Distance = 0.14*1.45/[0.14*2tan(70/2)] = 1.04 m
That's the distance between the license plate and the field of view, now I need to find the distance between Tareo and the field of view.
Tareo's head = 21.59 cm or 0.2159 m
Panel height = 1.27 m
Distance = 0.2159*1.27/[0.2159*2tan(70/2)] = 0.91 m
Now, to obtain the distance between the car and Tareo, I need to subtract the two previously calculated distances.
Distance = 1.04 - 0.91 = 0.13 m
With that distance, I can find the timeframe. The general speed limit in japan is 60 km/h or 16.6667 m/s, so I'm going to assume the car was moving at that speed.
Timeframe = 0.13/16.6667 = 0.0077999844000312 seconds
Finally, I can find Saitama's speed.
Speed = 4.27/0.0077999844000312 = 547.44 m/s
Saitama's Speed = 547.44 m/s, Mach 1.60 (Supersonic)
