Kevin wants to keep his heart rate at 160 beats per minutes. During his workout he counts 25 beats in 10 seconds.
A. How many beats per minute is this?

b. Should he workout a little harder (is he not at least at his target heart rate)?

Use a proportion.

25/10 = x/60

Cross multiply and solve for x.

Alright let me walk you through it.
10 * 6 = 60 seconds = 1 minute
Since he counts 25 beats per 10 seconds you do,
25 * 6 = 150
So, his heart beats 150 times per minute. Get it? Now you can do B.
