Question

What is the maximum speed that a human achieved and how?

Answer 1

Clue, Usain Bolt has the world record of 9.58 s in 100 m sprint.

Answer 2

It doesn't say "from the human's own power", so my guess would be some of the astronauts. In which case it would need to clarified what reference the speed is in relation to.

Answer 3

Ya, it doesn't say "from the human's own power", but the clue says Usain Bolt has the world record of 9.58 s in 100 m sprint.

Answer 4

Did the clue come from you? Or the exercise? It could be misleading.
I would at least point out that the question is ambiguous in this way, so you should answer something like "Assuming that 'self-powered' human speed is meant, ..."

Answer 5

And once you have that, the answer is _not_ 100/9.58 m/s.

Answer 6

Because that would be his average speed, not his maximum speed. The question cannot be answered without more data.

Answer 7

also, someone jumping off a cliff will be faster

Answer 8

What level of school is this?

Answer 9

http://hypertextbook.com/facts/2000/KatarzynaJanuszkiewicz.shtml

discusses the question; the fastest "instantaneos speed" is slightly below 12 m/s. The highest "average speed over 100 m" is what I mentioned above, which comes to slightly over 10.4 m/s.

Answer 10

Yeah. You're write. I should've acknowledge to you.

Answer 11

But i've asked this question for school kids who try to convert m/s in kmph for real world things. Anyway my question is not organised. I'll improve myself.
