A man covers first half of the distance with the speed V1 & the second half of the distance with the speed V2 . Then find its average speed.
Asked by ananya vyas | 6th Apr, 2011, 04:15: AM
Let the total distance be 'd'.
Time taken in 1st half = (d/2)/V1
Time taken in 2nd half = (d/2)/V2
Av. velocity = total distance / total time taken.
Hope this helps.
