Question

An aeroplane flies 2695km in 3h 30minutes. How long will it fly a distance of
6160Km at the same speed

Answer 1

$$\begin{gathered} \mathrm{Distance}\mathrm{covered}\mathrm{by}\mathrm{aeroplane}=2695\mathrm{km} \\ \mathrm{Time}\mathrm{taken}=3\mathrm{h}30\min =3\frac{30}{60}\mathrm{hr}=3\frac{1}{2}\mathrm{hrs}=\frac{7}{2}\mathrm{hrs} \\ \mathrm{Speed}\mathrm{of}\mathrm{aeroplane}=\frac{\mathrm{Distance}}{\mathrm{time}}=\frac{2695}{7/2}=770\mathrm{km}/\mathrm{h} \\ \mathrm{Time}\mathrm{taken}\mathrm{to}\mathrm{cover}6160\mathrm{km}=\frac{\mathrm{Distance}}{\mathrm{speed}}=\frac{6160}{770}=8\mathrm{hrs} \end{gathered}$$
