The hand represents the radius of the circle of the clock, so we would want to find the perimeter of the circle to begin with to determine how far the point of the hand would travel full circle (12 hours) To do this we would use the equation 2(pi*radius) we would use 3.14 as pi in this equation.
p=2(3.14*7) solves to 43.98 inches. This means the point of the hand travels 48.98 inches in 12 hours, to find how far it moves in just one hour, we would divide 43.98 by 12. This gives us the final answer of 3.665 inches traveled in one hour.
