Explanation / Answer
same thing as the water bottle problem. In this case... . radius is reduced by25% so newradius = 0.75 * old radius . and speed * r2 for old = speed* r2 for new . new speed / oldspeed = r2 /(0.75r)2 = 1.778 . The speed of the blood in the artery must increase by a factorof 1.778 or 77.8% increase in speed
