Q1. A business jet burns 300 gallons of gasoline per hour. How many gallons of gasoline will the jet burn in a three hour flight?

Let the number of gallons required in 3 hours be = x

\frac{x}{3}=\frac{300}{1}

x=900 gallons.

Answer: The business jet burns 900 gallons of gasoline in a three hour flight.

Q2. On average, one gallon of gasoline weights approximately six pounds. How many pounds does fifty gallons of gasoline weigh?

Let the weight in pounds of 50 gallons be = x

\frac{1}{6}=\frac{50}{x}

x=300 pounds

Answer: Fifty gallons of gasoline weighs 300 pounds.

Q3. For every one yard, there are thirty-six inches. Convert 2,124 inches to an equivalent number of yards.

Let the number of yards be = x

\frac{1}{36}=\frac{x}{2124}

36x=2124

x=\frac{2124}{36}=59 yards

Answer: 2,124 inches = 59 yards

Q4.  A person who weighs 240 pounds burns 180 calories per mile of running. If a person burns thirty-six calories by running one mile, how much does the person weigh?

Arte-miy333 [17]
Although the graph is not given in the option, so I would consider it from a different graph with the same question. The graph that represents the area of each rectangle in terms of the change in the length and width is the one with coordinate points located on the grid. The coordinate points on the form of (x,y) are represented as: 

1. (0,40)
2. (1,45)
3. (2,47) 
4. (8,25)

Hence,The graph with these coordinate points will be representing the situation.
