1.	A car covers two fifths of a 150-km road with a velocity of 60 km/h east and then continues to cover the rest towards the east in another hour. Find its average speed and average velocity (in km/h).
Answer» Letx consider, x= TOTAL DISTANCE covered by the car,Time taken to complete the half distance with VELOCITY v=40km/h,t 1 = 2×40x = 80x HR. . . . .(1)The time taken to complete another half distance with velocity u=60km/ht 2 = 2×60x = 120x hrThe total time taken, t=t 1 +t 2 t= 80x + 120x = 48X hrThe average speed of the car, v avg = x/48x =48km/h
