Answer

Since $Volume/sec = Area\times velocity$ is constant and diameter of artery is more than that of capillary, speed of blood should be more in capillary. But this is not the case since blood which is flowing in artery divides into various capillaries and the area of cross-section combined of various capillaries is greater than the artery so speed in each capillary is less than the speed of blood in artery.
