Answer:
220 hp
Explanation:
Let the input horsepower of the engine = x
The engine has a 5% loss of power, therefore, its output is:
[tex](100-5)\%\text{ of x}=95\%x=0.95x[/tex]Given that the engine's output = 209 hp.
[tex]0.95x=209[/tex]Divide both sides by 0.95 to solve for x:
[tex]\begin{gathered} \frac{0.95x}{0.95}=\frac{209}{0.95} \\ x=220\;hp \end{gathered}[/tex]The input horsepower of the engine is 220 hp.
