Answer:

Ali's heart rate is 135 times per minute.

Step-by-step explanation:

Let Ali's heart rate be denoted by <em>x</em> times per minute.

It is provided that Ben's heart beats 18 times per minute more than Ali.

The ratio of their heart rates was 15:17.

That is:

$\frac{15}{17}=\frac{x}{x+18}$

Solve for <em>x</em> as follows:

$\frac{15}{17}=\frac{x}{x+18}$

$15(x+18)=17x\\15x+270=17x\\2x=270\\x=135$

Thus, Ali's heart rate is 135 times per minute.
