My new answer:
Usain Bolt acheived a top speed of 27.28 mph or43.90 kph in travellng the 2 fastest consecutive 60-70 & 70-80, 10m splits ever of .82 seconds.
We'll leave out 4x100m splits as I don't have them for Team Jamaica's WR from Beijing.
Old answer:
Since Usain Bolt became the 100m WR holder with a 9.68, I don't know if this figure still stands but in the 1996 Atlanta Olympics, Donovan Bailey in a WR time of 9.84 secs, covered a 10m portion at 12.1 meters per second. That would translate to about 27 MPH or about 43 Km/h. Both he and Maurice Greene hit a 10m section of the 100m final of the 1997 World Championships at 11.91 m/s... Greene ran a 9.86 and Bailey ran a 9.91. That would mean both reached a speed of roughly 26.5 MPH. Considering that, even the reductions the WR has taken in the last 12 years, it would be okay to assume 27-28 MPH is the fastest speed ever attained by a person running. Though Bob Hayes, in 1964, ran his leg of the 4x100m relay in 8.50 seconds.
Answer: 30 km/h = 18.6411 mph
29.92 mph
To find the distance he is from work, we can use the formula: distance = speed x time. If he is averaging 30 mph for 30 minutes (0.5 hours), the distance he is from work would be 15 miles (30 mph x 0.5 hours).
Yes.
That event occurred in 1960. Martin Luther King Jr. was arrested in Georgia for driving 30 mph in a zone of 25 mph.
A Hippo can run from 18 mph / 30 khm; to 30 mph / 50 khm and the "Average Human" can run between 14 and 27 mph (Olympic sprinters ignored for the purposes of this question) - so the answer would be that a Hippo can, on average, outrun a human.
Faster than any human can run, that is 60 miles per hour. The fastest man ever has never ran faster than 30 mph. A mile a minute is IMPOSSIBLE for a human being.
I would say 6 and above. I would say 6 mph and above.
40km/h
20 to 30 mph
20 to 30 mph
30 mph
about 30 mph!
2.25 miles
No. The top speed for this species is around 30-35 mph.
50 mph for 160 yards
No; a grizzly bear can run about 30 MPH. A horse can run about 40 MPH. Horse speed can vary by breed, however.
