## Solution

Time taken by Amrita to travel $$720\ km =18\ \text{hours}$$
Time taken by Amrita to travel $$1\ km =\frac{18}{720}\ \text{hours}$$
Therefore, time taken by Amrita to travel $$360\ km =\frac{18}{720}\times 360\ \text{hours}$$
$$=\frac{18}{2}\ \text{hours}$$
$$=9\ \text{hours}$$
Hence, time taken by Amrita is $$9\ \text{hours}$$.
