10.
The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The ship uses 30 barrels of oil in traveling 85 miles at 42 mi/h. How many barrels of oil are used when the ship travels 26 miles at 54 mi/h? Round your answer to the nearest tenth of a barrel, if necessary. (1 point)
2.3 barrels
15.2 barrels
49.6 barrels
9.2 barrels

I got Amount of oil = k(26)(54)^2 Im not sure what to do after i solve (26)(54)^2. I got 75,816. So now its Amount of oil = 75,816k. Now what?
