Answer:
Usain Bolt speed in 2008 summer Olympics in Beijing, China is 10.36 meters per second or 37.30 kilometers per hour
Solution:
Speed = Distance ÷ Time
First, divide 200 by 19.30; then just round it to the nearest hundredths because it is so long to write like the procedure below.
200 ÷ 19.30 = 10.3626943005181
10.3626943005181 = 10.36
To convert it to kilometers per hour. Multiply it by 3600 and then divide it by 1000 if u like to round it just round it you know how to round it to the nearest hundredths like the procedure below.
10.36 x 3600 = 37296
37.296 ÷ 1000 = 37.296
37.296 = 37.30
Hope you appreciate my work.
