I would say anywhere between 4.8 seconds and 5.5 seconds would be "average" / "normal". But there are a lot of factors as presented in many of the other answers.
It's a 5.04 now
I would say that it depends on the IHOP early bird special.
Pretty fast, but depends on how developed you are. If you are already a MAN then its okay..
It all depends on your weight and height and of course how fast you are but an average time for a 40 yard dash is 6.2 s ( or 6.7-7.3s) if you've heard 5.5 s than you're mistaken. That's definitely not an average time , that's more like a pretty fast time.
My son is ten and ran it in 4.78 seconds
about 60 seconds.
Bob Hayes has the world record in the 100 yard dash. This record was set in the year 1963. This is a separate race from the 100 meter dash.
chris Johnson is very fast at a 4.2 40 yard dash. and bush is right behind him at 4.3
my brother goat sets the record for best 40 yard dash time and its 4'01
It could be anywhere from 5.5 to 4.9 seconds depending on how tall you are and how fast you accelerate.
A 10 yard dash time is really not a good judge of your speed, the distance is too short. A 40 yard dash is what you need to get a good estimate of your abilities. but I'll give you time for both 40 yard dash-between 5-5.8 seconds 10 yard dash-between 1.3-1.5 seconds
Mostly, it depends on what you do daily. I'd say that your 4.59 40 yard dash is okay.
