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.
19.62 seconeds by Usain Bolt in 2008 Olympics
American Sprinter: Micheal Johnson who broke world Records in Atlanta 200 meter dash 19.32 sec ---- Prior to Usain Bolt breaking the 100 meter dash record in New York in May, 2008 and then breaking his own record at the 2008 Summer Games in Beijing, the world record holder in the 100 meter dash was Asafa Powell of Jamaica who ran a time of 9.74 seconds.
it would depend on how hot or cold it is.
Subtract one hour from a BST time to convert to GMT. To do the opposite, add one hour to a GMT time to convert to BST.
These are all easy to find in your book: Length . . . . . . . Meter Mass . . . . . . . . . Kilogram Volume . . . . . . . Cubic Meter (* Liter is 1/1000th m3, or one dm3) Density . . . . . . . Kilogram per cubic meter Time .. . . . . . . . . Second Temperature . . . Kelvin or Celsius degree (same size)
A reliable way to convert a hand-held 100-yard time to an electronic 100-meter time is to multiply the hh-time by 1.103. Therefore, 10.2 in the 100-yard dash time equates to an 11.25 100-meter dash time. Also, to convert an electronic 100-yard dash time to an electronic 100-meter dash time, multiply the first time by 1.088. For example, a 10.20 electronic 100-yard time equates to an 11.10 electronic 100-meter dash time.
75 yards is 68.58m so to convert 8.3s for 75 yards to 70m: = 70/68.58 x 8.3 = 8.47s
A 220 yard dash time of 21.80 seconds translates to a time of 21.67 seconds for 200 meters.
A 12.5-second 100m equates to a time of 4.572 seconds in the 40-yard dash.
You could get a rough estimate by dividing by 60, and multiplying by 55. However, you can't really convert from one to the other, because the human body doesn't work that way.
To convert a hand-timed (1/10 of a second) 100-yard time to and auto-timed (1/100 of a second) 100-meter time, multiply the hand-time by 1.082. To convert an auto-timed 100y to an auto-timed 100m time, use 1.11.
You can't. It would be like extrapolating a marathon time from a mile time.
it depends on the age group. 15 seconds is a decent time for a grade school 100 meter dash, but it would be a decent time for a high school 200 meter dash.
His 5.0 40-meter dash translates to a time of 4.572 seconds in the 40-yard dash.
10.7 100 meter dash = 9.78 100 yards
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
The projected time would be 4.206 seconds for the 40-yard.
