c.24 km

d.16 km

Answer 1

I think it is 20 km :)

Answer 2

Answer:

B is the correct option.

Explanation:

Let us draw a diagram for the given situation.

Let us suppose A be the starting point. The man runs 4 km towards north and reaches at point B. Now he runs 20 km towards east and reaches at point C. Finally he runs 4 km towards south and reaches at point D. We have to find the length of AD.

From the attached diagram, we can see that

AB = 4

BC= 20

CD = 4

This is a rectangle. Hence, we can say that

AD = CD

AD = 20

Therefore, the man is 20 km far from his starting point.

B is the correct option.
