Question
A particle moving in a straight line covers half the distance with speed of 
. The other half of the distance is covered in two equal time intervals with speed of
and 
respectively. The average speed of the particle during the motion is
The correct answer is:
If 
and
are the time taken by particle to cover first and second half distance respectively
…(i)
and 
So, 
(ii)
Total time 
So, average speed
