The force F needed to loosen a bolt with a wrench varies inversely with the length l of the handle. Write an equation relation F and l, given that 250 pounds of force must be exerted to loosen a bolt when using a wrench with a handle 6 inches long. How much force must be exerted when using a wrench with a handle 24 inches long? State the exact answer, do not round.
