36. When running at 64% of its potential power, an aircraft engine consumes fuel at a rate of 11.5 gallons per hour. When running at 70% of its potential power, the engine consumes fuel at a rate of 14.7 gallons per hour. The rate of fuel consumption is linearly related to the percent of potential power. Which of the following is the best estimate of the fuel consumption of the aircraft engine, in gallons per hour, when running at 60% of its potential power?

Answer and Explanation

Your Answer is

Correct Answer is K

Explanation

Because the fifth line in the question stem says that fuel consumption and potential power are in a straight line relationship, so according to the information in the first four lines, two coordinate points on this line can be obtained. According to these two points, the analytical formula can be obtained, and then the potential power=0.6 can be substituted.
