Question

A car is moving along x axis .it moves from o to p in 18 secs and from p to q in 6 secs . Calculate the av.speed and av.velocity of the car in going from 1) o to p 2) from o to p and back to q

Answer 1

Assuming from your question that the points o,p and q lie as follows
O---Q---P
Since the trajectory is along the x-axis

Avg speed(o to p) =
distance between o and p / 18

Avg velocity(o to p) =
Distance between o and p / 18

Avg speed ( o to p to q)=
Distance between o and p + distance between p and q / 18+6

Avg velocity (o to p to q) =
Distance between o and q/18+6
