there is no way you can tell everyone is different some people are super fast at the 20 and drop majorly at the 40. But ruffly i would double and add .81 seconds

According to this guy’s guidelines, the 40yard time is a little more than 70% longer than the 20yard time. So with your numbers, you’d be between 4.8 and 5.2.

Why not just run 40 yards, and have someone time you?
Sarge

The derivative of your 20 yard time x the square root of your height divided by your shoe size. Then square all of that.

you have to figure out your top speed in 10yds and multiply that by 2 and add it… or you can just run 40 yards. its not that far.

Its just not possible sorry, try doing that in a corvette

dude it depends when you reach max peed, after that, it you slow down. try to go for a more gradual increase.
The amount of time a person or object takes to travel 40 yards can easily be converted to miles per hour with the simple formula below. Please consider the discussion of some limitation following the formula.
mph = 3600 / (seconds * 44)
The major assumption with this formula is that all subsequent forty yard intervals in a mile (44 intervals) will be covered in the same amount of time.
Most users of this calculator will likely be interested in converting their 40yard dash times in football drills to miles per hour. Consider that during the forty yard dash there is an acceleration period so a person will not be running a constant speed, also it is not a sustainable pace to run for an entire mile. Therefore this is a largely theoretical calculation for the interest of comparison.
A person’s maximum speed measured at an instance in time will likely be higher.
40Yard Dash to Miles per Hour Variables
To Calculate miles per hour a distance and time is required. Since the distance is set at 40 yards we only need a time to complete the calculation.Time in Seconds (s)Measured number of seconds to complete the forty yard dash. Any number of decimals may be used but most measurements of forty yard dash times use two decimals.Miles per Hour (mi)Number of miles that would be travelled in one hour if the exact same pace in the first 40 yards were maintained for an entire mile. Abbreviated mph or mi/h; in the calculator table abbreviated mi since fields in the calculator table may only be presented with one or two letters.
40Yard Dash to Miles per Hour Solution
If a running back has a 40yard dash time of 4.5 seconds what would this be in miles per hour?
mph = 3600 / (seconds * 44)
Formula to convert forty yard times to miles per hour
mph = 3600 / (4.50 * 44)
Substitute in your forty yard dash time in seconds
mph = 3600 / 198
Calculate the brackets to get the number of seconds it would take to run a mile
mph = 18.18
Divide the number of seconds in an hour, 3600, by your time per mile, 198. The answer is rounded to two decimals
18.18 mph
A 40yard dash completed in 4.50 seconds would be about 18.18 miles per hour (mph), after rounding to two decimals. Convert 18.18 miles per hour to kilometers per hour using the online converter.
40Yard Dash to Miles per Hour Example
If a wide receiver runs a 40yard dash in 4.45 seconds what is the theoretical speed in miles per hour?
mph = 3600 / (seconds * 44)
mph = 3600 / (4.45 * 44)
mph = 3600 / 195.8
mph = ~18.39
Approximately 18.39 mph
A wide receiver running 40yards in 4.45 seconds would run about 18.39 miles per hour if they maintained the 40yard pace. Answer rounded to two decimals.
