A car moves from city A to city B on a straight line and then comes back. While moving from A toB, it covers first half of the distance at a rate of 40 km/h and next half with 60 km/h. While movingback from B to A, it moves with 40 km/h for half the time and 60 km/h for remaining half time. Findits average speed and magnitude of average velocity (0) during its motion from A to B (ii) during itsmotion from B to A.

1.	A car moves from city A to city B on a straight line and then comes back. While moving from A toB, it covers first half of the distance at a rate of 40 km/h and next half with 60 km/h. While movingback from B to A, it moves with 40 km/h for half the time and 60 km/h for remaining half time. Findits average speed and magnitude of average velocity (0) during its motion from A to B (ii) during itsmotion from B to A.
Answer» <p>(1) From A to Bx/(x/40+x/60) =24 km/hr(2) From B to A(40t+60t) /2t= 50km/hr</p>
