Question

$$\begin{gathered} \mathrm{Fill}\mathrm{in}\mathrm{the}\mathrm{blanks}: \\ ...........\mathrm{m}=2.180\mathrm{km} \end{gathered}$$

Answer 1

$$\begin{gathered} \mathrm{Since},1\mathrm{km}=1000\mathrm{m} \\ So,2.180\mathrm{km}=2.180\times 1000\mathrm{m}=2180.0\mathrm{m}\mathrm{or}2180\mathrm{m} \\ \mathrm{Hence},2180\mathrm{m}=2.180\mathrm{km} \end{gathered}$$
