you should provide us exactly what Jet is capable of, Dekiru, because speed-wise, i would have said he was about (going based on what VS Wiki has) Superhuman. now, i didn't want to bore any readers of my Gaster/Frisk post with some math, but i'll provide the distance of the fire in the exact moment it was heading towards Silver and Blaze.
the fire was traveling at around 30 mph when fired at Jet, who was about 20 feet away at the given time. this means that it would have taken the columns 1 full second to travel 44 feet, or more accurately, 43.99999999999999 feet. that's over twice the distance from Jet. this means it would have taken the column 0.4545468, or simply 0.45 seconds to reach Jet's position, basing on a distance of 20 feet. Silver and Blaze appeared three quarters along that length, so about 15 feet ahead of the Hellhound, and 5 feet in the way of Jet.
this means it would have taken the flames 0.340909, or 0.34 seconds to reach Silver and Blaze. by the time they appeared, the column was mere inches in front of them. let's say, for accuracy... 3 inches. that means it would have taken 0.00568182, or 0.006 seconds for the flames to hit Silver and Blaze, giving them little to no reaction time. Jet, however, moved in and blocked the columns of fire. He was only 5 feet behind Silver and Blaze. We have the distance, but we don't know the speed he went, or the time it took to get there, so allow me to do some more math.
in order to do this, i will be taking Jet's original max speed i believed he was capable of, which was superhuman, but for simplicity, i will select superhuman, which is a max of 34.3 meters per second, which is 112.5328 (112.5) feet, according to VS Wiki. that means, in order to get in front of Silver (rounding down the added inches for simplicity's sake), the absolute maximum he would be able to move would be in 0.0444315, or 0.04, seconds. this, however, is far too slow for 0.006 seconds, so we have to up his speed from superhuman to subsonic. the max speed subsonic can go is 171.5 meters per second, or 562.66404 (562.7) feet.
this just
barely doesn't make it, clocking in at 0.0088863, or 0.009, seconds. i had to up the game again, from subsonic to subsonic+. the max speed for this category is 308.7 m/s, which is 1012.7953 (1012.
feet. this time, the speed is almost to make it, just barely, coming in at 0.00493683, or 0.005, seconds. this means Jet has to be halfway through subsonic+ or above. the bare minimum he could have gone, however, 0.006 seconds to be exactly on time. he would have had to have moved 833.333 feet per second.
now, i could just wrap this up and say i'm done, but we need to also account for reaction time. it takes the average human 0.13 seconds to process basic information and react to it. if this was the base for Jet, then this would already have failed, even if he had instantaneously teleportation. so i need to lower Jet's reaction time down to a minimum of 0.0059 seconds, allowing 0.0001 seconds for Jet to react, meaning he would have to travel at 50,000 feet per second, which is 15,240 meters per second, which equals to 13.542717 (13.5) times the speed of sound, which would place Jet much higher, at Hypersonic+, passing by Transonic, Supersonic, Supersonic+, and Hypersonic. that's hella fast.
sorry to bore you all with math. i wanted a chance to do it, as i don't have a math class this year, and i love math. i could do some math on other characters if anybody wants, as it would be super duper fun for me.
anyway, Dekiru. just how fast is Jet? i need an absolute maximum.
again, i know i didn't provide the exact distance and other math stuff in my post, but now that i've estimated it, i would like to know just how fast Jet is.
