at 70% an engine produces 1250 hp, what is the max output hp? (nearest whole number)
1,786

Explanation:

Step1: Calculate the percentage for the first - part

The formula for percentage is $\frac{\text{Part}}{\text{Whole}}\times100\%$. Here, the part is 20 hp and the whole is 300 hp. So the percentage is $\frac{20}{300}\times100\%=\frac{2000}{300}\% \approx 6.67\%$, rounded to the nearest whole number is 7.

Step2: Calculate the maximum output for the second - part

Let the maximum output be $x$ hp. We know that 70% of $x$ is 1250 hp. So we can write the equation $0.7x = 1250$. Solving for $x$, we get $x=\frac{1250}{0.7}\approx1785.71$, rounded to the nearest whole number is 1786.

Answer:

7
1786
