Given:
The speed of the beetle is, s = 9 km/h.
The objective is to convert the speed into centimeters per second.
Explanation:
Since, it is known that,
[tex]\begin{gathered} 1\text{ km=1,00,000 cm} \\ 1\text{ hour=3600 s} \end{gathered}[/tex]Conversion;
Then, the speed can be converted as,
[tex]\begin{gathered} s=9(\frac{km}{hr})(\frac{1,00,000\text{ cm}}{1\text{ km}})(\frac{1\text{ hr}}{3600\text{ s}}) \\ =250\text{ cm/s} \end{gathered}[/tex]Hence, the the converted value is 250 cm/s.
