Question

A particle moving in a straight line covers half the distance with a speed of 3m/s. The other half of the distance is covered in two equal time intervals with speeds of 4.5m/s and 7.5m/s respectively. The average speed of the particle during the motion is?

Answer 1

Here Total distance is taken as s, AO is the half the distance s, i.e. s/2 and OB is the other half. The time t/2 is taken for OP and PB also does so. Total time taken for OB is t seconds.

It's a conceptional question
