Question

A cyclist travels 12 km in 3 hours. In how many hours will he travel 20 km?

Answer 1

Dear student
$$\begin{gathered} \mathrm{Time}\mathrm{taken}\mathrm{to}\mathrm{travel}12\mathrm{km}=3\mathrm{hours} \\ \mathrm{Time}\mathrm{take}\mathrm{to}\mathrm{travel}1\mathrm{km}=\frac{3}{12}\mathrm{hours}=\frac{1}{4}\mathrm{hours} \\ \mathrm{Time}\mathrm{take}\mathrm{to}\mathrm{travel}20\mathrm{km}=20\times \frac{1}{4}\mathrm{hours}=5\mathrm{hrs} \end{gathered}$$
