Answer on Question #48385, Physics, Mechanics - Kinematics - Dynamics

A man is running 2000 CM in 30 seconds. Find how much KM he run in 30 seconds?

Centi is $10^{-2}$, so distance $2000\,cm = 2000 \cdot 10^{-2}\,m = 20\,m$

Kilo is $10^{3}$, so distance $20\,m = \frac{20}{10^{3}}\,km = 0.02\,km$

Answer: $0.02\,km$
