A body travels with velocity ` v_(1) for time ` t_(1)` second and with velocity ` v_(2) for time t_(2) second in the same direction, fide the avetage velocity of the body.

Explanation

Displacement travlled in time (t_(1)-t_(2))
` =v_(1) t_(1) +v_(2) t_(2)`
:. Average ve,pcoty =(displacement )/(total time taken)
`= (v_91) t_(1) + v_(2) t_(2))/((t_(1) +t_(2))`.
