A body travelling along a straight line traversed one thired of the total distance with a velocity 4 ms^(-10 . The remaining part of the distance was covered with a velocity 2 ms^(-1) for half the time and with velocity 6 ms^(-1) for the other hald of time . What is the mean velocity averaged over te whle time of motin ?

A particle travels half the distance with a velocity of 6 ms^(–1) . The remaining half distance is covered with a velocity of 4 ms^(–1) for half the time and with a velocity of 8 ms^(–1) for the rest of the half time. What is the velocity of the particle averaged over the whole time of motion ?
