Answer:


69\text{ hp}

Step-by-step explanation:

Here, we want to get the amount of horsepower produced by the engine at 2300 rpm

From the question, we have :

60 hp produced at 2000 rpm

At 2,300 rpm, there would be 15% increase in hp

Thus, at 2300 rpm, the hp would be:


\begin{gathered} 60\text{ + 15\% of 60} \\ 60\text{ + }(15)/(100)*60 \\ \text{ = 60 + 9 = 69 hp} \end{gathered}

Thus, this means that the engine produces 69 hp at 2300 rpm
