An ancient warship once covered 180 sea miles in 24 hours. explain why at some point during this feat the ship's speed exceeded 7.3 knots (sea miles per hour).

Average speed is 184/24 = 7.667 knots

Explanation:

The average speed is 184/24 = 7.667 knots and by the Mean Value Theorem that speed must have been traveled at some point.

Mean value theorem :

It states that if f(x) is defined and continuous on the interval [a,b] and differentiate-able on (a,b), then there is at least one number c in the interval (a,b) (that is a < c < b) such that:

f'(c)=(f(b)-f(a))/(b-a)

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
