Actually I am in high school I just want to confirm that whether two figures of this question possible:
Question is :
A car is moving along a straight line OP.It moves from O to P in 18 seconds and returns from P to Q in 6 seconds , where OP = 360 metres and OQ = 240 metres.What are the average velocity and average speed of the car is going (a) From O to P and back to Q?
My physics teacher made this figure from the question:
and I this figure is also right:
But When I solve the above Question by first figure I got Average speed of 20 m/s and 40 m/s from 2nd figure.
Which one is correct?
(When I ask my Question to my physics teacher , He said "First one is correct,Second one doesn't make any sense")
