Answer 1

Dear student
$$\begin{gathered} \mathrm{Given}: \\ \mathrm{Distance}\mathrm{between}\mathrm{city}\mathrm{A}\mathrm{and}\mathrm{city}\mathrm{B}=500\mathrm{km} \\ \mathrm{Distance}\mathrm{between}\mathrm{city}\mathrm{B}\mathrm{and}\mathrm{city}\mathrm{C}=200\mathrm{km} \\ \mathrm{So},\mathrm{exact}\mathrm{distance}\mathrm{between}\mathrm{city}\mathrm{A}\mathrm{and}\mathrm{city}\mathrm{C}\mathrm{is}\mathrm{given}\mathrm{by}: \\ =\mathrm{Distance}\mathrm{between}\mathrm{city}\mathrm{A}\mathrm{and}\mathrm{city}\mathrm{B}+\mathrm{Distance}\mathrm{between}\mathrm{city}\mathrm{B}\mathrm{and}\mathrm{city}\mathrm{C} \\ =\mathrm{km}\left(500+200\right) \\ =700\mathrm{km} \end{gathered}$$
