Two runners A and B start simultaneously from the two points on the circle x2 + y2 = 16 where it cuts the X-axis. The speeds of A and B are in the ratio 1 : 2 and they are moving in opposite directions. Bookmark Add Bookmark|
If A starts from the point where the circle cuts the negative X-axis, then find the distance covered by A before they meet
i am getting 8pi/3
but the answer is (a) how?
|How did you get 8pi/3?|
|Both A and B start from opposite ends of x- axis so consider only half of circumference so it is 4 pi/3 only|
