An empty Boeing 747 weighs about 175 tons. How much does it weigh in ounces? If this same Boeing 747 burns about 10 tons of fuel per hour when at cruising altitude, determine the mumber of gallons per minute this jet consumes (assuming jet fuel weighs about 6.8 lbs per gallon). At $4.55 per gallon for jet fuel, how much will fuel cost for a 4-hour flight?

Question
An empty Boeing 747 weighs about 175 tons. How much does it weigh in ounces? If this same Boeing 747 burns about 10 tons of fuel per hour when at cruising altitude, determine the number of gallons per minute this jet consumes (assuming jet fuel weighs about 6.8 lbs per gallon). At $4.55 per gallon for jet fuel, how much will fuel cost for a 4-hour flight? A 747 can carry up to 467 passengers. How much would each have to pay just to cover fuel costs for the flight? A Jacuzzi was filled with 200 gallons of water. The Jacuzzi itself weighed 50 1b. If a person who weighs 60 kg and another who weighs 105 kg get into the Jacuzzi, how much is the total weight in pounds including the two people, the tub, and the water? (Hints: 1 kg = 2.21bs, convert gallons -> cubic feet -> pounds).
