1.	A car moves from x to y with uniform speed v1 and returns to y with a uniform speed of v2 .average speed for this round tripp is
Answer» tion:AVERAGE is given by TOTAL DISTANCE / total timelet'sbassume the distance between x and y is d so, the time taken to GO from x to y will be d/ v1and , the time taken to go from y to x will be d/v2so, the average speed will be=2d/ d/V1+d/v2=2d v1 v2/ v1 + v2
