D.
According to the Question we can draw the following Diagram-
It is clear from the above diagram that, B is in the West direction from A.
Distance between A and B = 25 – 10 = 15
Hence, option B is the correct answer.
Required distance=square root of (482+552)
=73km
B.
From the above diagram, it is clear that the houses of C and D are less than 20 km apart.
Hence, option C is the correct answer.
From the statements in the question we can make the diagram as shown:
Using Pythagoras theorem in triangle ABC
(AB)2 + (AC)2 = (BC)2
(5)2 + (12)2 = (BC)2
(BC)2 = 169
BC = 13 km
Hence, option D is correct.
