Answer:
375km
Explanation:
The tourist has already covered 3% of the journey.
So the remaining distance to be covered is 64% f the total journey.
(100% - 36% = 64%)
Therefore 64% of the journey = 240km
Then 100% of the journey:
y km --> 100%
240 km --> 64%
Total length of the route = 240 km * (100/64) = 375km
