If a battleship fires a 50 lb shell with roughly 8 lbs of gunpowder out of a 13 foot long barrel raised at 45°, at what speed will the shell leave the barrel, and how far will said shell go before hitting the water?

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
