Question

if an engine is rated at 297 hp max, and it is running at 55% power, what hp is being developed? (2 decimals if needed)

Explanation:

Step1: Convert percentage to decimal

To use the percentage in a calculation, convert 55% to a decimal. We do this by dividing 55 by 100. So, $55\%=\frac{55}{100} = 0.55$.

Step2: Calculate the power developed

Multiply the maximum - rated power of the engine by the decimal - equivalent of the percentage of power it is running at. The maximum - rated power of the engine is 297 hp. So, the power developed $P$ is given by $P=297\times0.55$.
$P = 297\times0.55=163.35$ hp.

Answer:

163.35
