Answer 1

The correct option is A 12 km

Method 1:
This question can be easily solved using the options.
Option (a) fits the given situation best as if we take the distance as 12 km she would have taken 1 hour to go by car and 4 hours to come back walking - a total of 5 hours as given in the problem.

Method 2:
$\frac{x}{12}+\frac{x}{3}$ = 5
Solving, x = 12km
