A particle travels first half of the total distance with speed `v_1.` In second half distace with speed in1/3 rd timeis `v_2.` and in remaining 2/3 rd time constant speed is `v_3.` Find the average speed during the complete journey.

A person travel first half of the total distance with speed v_(1). In the second half distance, constant speed is (1)/(3)rd time is v_(2) and in remaining (2)/(3)rd time the constant speed is v_(3) The average speed during the complete journey is:
