Answer 1

We convert centimeters to meters by using the conversion factor below:

\[24 cm *(\frac{ meter }{ 100cm }) = \frac{ 24 }{ 100 } = 0.24meter\]

then we convert meters to kilometers by multiplying meters by the conversion factor below. notice that the units for meters cancel out and we're left with kilometers as the answer.

\[0.24meters*(\frac{ Km }{ 1000meters }) = (\frac{ 2.4x10^{-1} }{ 1.0x10^{3}}) = 2.4x10^{-4} km \]

Answer 2

\[2.4x10^{-4} = 0.00024\]
