    D)   27 km

    E)             None of these

    Correct Answer: D

    Solution :

    Explanation Option [d] is correct. \[\operatorname{A}s distance = 5 \times  3 = 15 km.\] \[\operatorname{B}s distance = 4 \times  3 = 12 km.\] \[\operatorname{B}s distance = 4 \times  3 = 12 km.\] \[\therefore \] Distance between the two \[\,= 15 + 12 = 27 km\] (Because they are walking in opposite directions).
