Question

Helpppp meeeee plzzzzzzz

Answer 1

well, there are 1000 meters in a kilometer, and there are 100 meters right now. 100x10=1000, so therefore 9.69 sec x 10 = 96.9. So, he could run 1 km in 96.9 sec.

There are also 100 cm in a meter. so, 100 cm x 100 meters is 10,000 cm. therefore, he could run 10,000 cm in 9.69 sec.

Technically, he is also fast enough to run 1 cm in 96.9 sec then, too.

I'm not sure about the others though, I'm sorry.
