A particle Travels the first half of its Total distance along a straig

1.	A particle Travels the first half of its Total distance along a straight line with a speed V kilometre per hour then next half with a speed of 60 km per hour the average speed for the total journey is 40 kilometre per hour then value of v is
Answer» 20 km/hrExplanation:AVERAGE SPEED= (v+60)/240=(v+60)/280-60=vv=20km/hr
