Question

a car travels 244 1/2 km in 6 hours . find the speed of car.

Answer 1

$$\begin{gathered} \mathrm{Distance}\mathrm{travelled}=244\frac{1}{2}\mathrm{km}=\frac{489}{2}\mathrm{km} \\ \mathrm{Time}\mathrm{taken}=6\mathrm{hours} \\ \mathrm{Speed}=\frac{\mathrm{distance}}{\mathrm{time}}=\frac{489}{2}÷6=\frac{489}{2}\times \frac{1}{6}=\frac{163}{4}=40\frac{3}{4}\mathrm{km}/\mathrm{h} \end{gathered}$$
