Answer

Explanation:

Step1: Find high - speed fuel values

For high - speed (yellow line), at 1 hour, fuel is 819 lb and at 2 hours, fuel is 1242 lb. The change in fuel $\Delta F_{h}=1242 - 819=423$ lb.

Step2: Convert to gallons

Since 1 gallon = 8.35 pounds, the rate $r_{h}=\frac{423}{8.35}\approx51$ gallons per hour.

Step3: Find long - range fuel values

For long - range (green line), at 1 hour, fuel is 683 lb and at 2 hours, fuel is 1242 lb. The change in fuel $\Delta F_{l}=1242 - 683 = 559$ lb.

Step4: Convert to gallons

The rate $r_{l}=\frac{559}{8.35}\approx67$ gallons per hour.

Answer:

  1. 51 gallons of fuel per hour
  2. 67 gallons of fuel per hour
