I was thinking the same thing but I found a solution:
Basically 1 second= 0.00027778 hours.
13mph- 0.06214(calculation of length of 100m)÷(0.00027778X13(your speed))
This equals=17.21 seconds as your 100m dash time.
It might look complicated but I simplified it.
World records for the 100-meter dash are . . .Men:Usain Bolt, August 16, 2009, 9.58 seconds = 23.35 mphWomen:Florence Griffith-Joyner, July 16, 1988, 10.49 seconds = 21.32 mph
The fastest human speed recorded is 27.8 mph, achieved by Usain Bolt during his 100m world record run in 2009.
speeds like mph are distance divided by time. So divide 100 meters by the dash time to get a speed. Then convert units to miles per hour. Or convert before you divide, meters to miles and dash time to hours.
I'm not exactly sure, but since I know that Usain Bolt ran a top speed of 27.9 mph in his 100m world record of 9.58 s, I would guess that Asafa Powel ran maybe 25-26 mph when he ran 9.72 s.
Usain Bolt's fastest recorded speed is about 12.27 meters per second, achieved during his world record-setting 100m sprint in 2009.
The average speed of the world record in the 100m dash is around 37.58 km/h (23.35 mph).
(100m/11.8s)(3600s/hr)(0.000621371192mi/m) = 18.9571mph So pretty much 19 mph.
Asafa Powell was clocked at 32 mph at his fastest point in the 100m dash when he ran his 9.74.but... it is wrong because Usain bolt ran .16 faster than him. at 33mph at an 100m dash...
19.2839 mph
Between 13-20 mph. The current world record for the 100m dash is 9.58 seconds. This translates to 23.4 mph. Instantaneous speeds off the line can hit up to 28mph for a short distance.
the fastest 100m dash was set by usian bolt with 9.69 seconds and for many olympic athletes their time averages around 10-11 seconds
A 5.7 second 40 yard dash is roughly equivalent to maintaining a pace of about 11 mph.
He is so fat that he can't even move so he has a special maid
19.3 miles per hour.
22.7 mph
Well, honey, if you're sprinting at 22 mph, you could cover 100 meters in about 4.55 seconds. But let's be real, unless you're Usain Bolt or a cheetah on steroids, you ain't hitting that speed anytime soon. So maybe stick to a more achievable pace and enjoy the journey instead of rushing to the finish line.
Cristiano Ronaldo can do 100m in about 10.61 seconds. The fastest football player ever is said to be amancio amaro who can do 100m in about 10.50 seconds.
