269702 If a body covers first half of its journey with uniform speed \(v\) and the second half of the journey with uhiform speed \(v_{2}\), then the average speed is

269703 \(A\) car is moving along a straight line, say \(O P\) in figure. It moves from 0 to \(P\) in \(18 s\) and return from \(P\) to \(Q\) in \(6 \mathrm{~s}\). W hat are the average velocity and average speed of the car in going from \(O\) to \(P\) and back to \(Q\) ?

269704 For a body moving with uniform acceleration ' \(a\) ', initial and final velocities in a time interval ' \(t\) ' are ' \(u\) ' and ' \(v\) ' respectively. Then, its average velocity in the time interval '\(t\) ' is
