The ship uses 112 barrels of oil in traveling 75 miles at 28 mi/h. How many barrels of oil are used when the ship travels 30 miles at 55 mi/h? Round your answer to the nearest tenth of a barrel, if necessary.

Answer 1

you don't say, but it appears that
fuel varies directly with distance and speed
If so, then you want
x/(30*55) = 112/(75*28)
x = 88 bbl
