What is the final horsepower when driving a car in Denver (an elevation of 5280 feet) rated at 300 Choices are A. 271.5 B. 252.48 C. 271.28 D. 250.4?

To calculate the final horsepower, we need to account for the decrease in air density at higher elevations. The air is less dense at higher altitudes, which means there is less oxygen available for combustion in the engine. This leads to a reduction in power output.

We can use the following formula to calculate the final horsepower:

Final Horsepower = Rated Horsepower * (1 - (0.03 * Elevation in feet / 1000))

Plugging in the values given in the question, we get:

Final Horsepower = 300 * (1 - (0.03 * 5280 / 1000))

Final Horsepower = 300 * (1 - 0.1584)

Final Horsepower = 300 * 0.8416

Final Horsepower = 252.48

Therefore, the final horsepower when driving a car in Denver is B. 252.48.
