A person walks distance of 4 km from his home in the north direction. Then he covers distance of 3 km in west direction. Now t from this place he direction walks toward home on the path of minimum distance between that place and home. What would be the total Home distance covered by this person?

A

5 km

B

7 km

C

12 km

D

zero

Text Solution

Verified by Experts

The correct Answer is:
C
From figure it is clear that minimum distance `= sqrt ((4) ^(2) + (3) ^(2)) = 5 km`
Hence, total distance coverd by the person `= 4 + 3 + 5 = 12 km`
