Question

airplane pilot
the graph below shows the rate at which fuel is burned when flying. note: 1 gallon = 8.35 pounds
1 what is the rate that fuel is burned when traveling at high speed? use the amount of fuel used between hours 1 and 2 to make your calculation
round your answer to the nearest whole number.
answer ______ gallons of fuel per hour.
2 what is the rate that fuel is burned when traveling at long - range cruise speed? use the amount of fuel used between hours 1 and 2 to make your calculation.
round your answer to the nearest whole number.
answer ______ gallons of fuel per hour.
time and fuel vs. distance

Explanation:

Step1: Identify fuel - amounts for high - speed at 1 and 2 hours

From the graph, for high - speed cruise, at 1 hour the fuel is 819 lb and at 2 hours it is 1174 lb.

Step2: Calculate fuel used in 1 hour

The fuel used between 1 and 2 hours is \(1174 - 819=355\) lb.

Step3: Convert pounds to gallons

Since 1 gallon = 8.35 pounds, the number of gallons is \(\frac{355}{8.35}\approx42\) gallons.

Step1: Identify fuel - amounts for long - range cruise at 1 and 2 hours

From the graph, for long - range cruise, at 1 hour the fuel is 803 lb and at 2 hours it is 1042 lb.

Step2: Calculate fuel used in 1 hour

The fuel used between 1 and 2 hours is \(1042 - 803 = 239\) lb.

Step3: Convert pounds to gallons

Since 1 gallon = 8.35 pounds, the number of gallons is \(\frac{239}{8.35}\approx29\) gallons.

Answer:

42
