a square path shown. The side of the square
is 18 km. He starts from position O, the mid--
point of side AD. in the direction shown. He
reaches point F. the midpoint of side CD. The
average velocity of the person is
(1) 6kmh west-south6
2)√2 km/hr southwest (3)3/√2km /hr southwest

Answer 2

Answer:

2

Explanation:

Calculate total time taken in journey and take displacement from initial point to final You may need to use pythagoras theorem there now just dividing the displacement by total time you will get final answer i.e. sqrt2 km/h southwest as position vector is towards South West direction.
