Question

If a car takes $24minutes$ to cover a $15km$ length of the road, how long will it take to travel $100km?$

Answer 1

Time taken to cover distance of $15km=24minutes$

So, the time taken to cover a distance of $1km=\frac{24}{15}minutes$

Now, the time required to cover a distance of $100km=\frac{24}{15}\times 100minutes$

$$\begin{gathered} =\frac{2400}{15} \\ =160minutes \end{gathered}$$

Hence, the time required to cover a distance of $100km$ is $160minutes.$
