To find Monica’s rate: 225 beats ÷ 3 minutes = 75 beats per minute
To find Jordy’s rate: 360 beats ÷ 5 minutes = 72 beats per minute

The answer is B, Monica had the faster heart rate of 75 beats per minute :)

If Monica's heart beat is 225 times in 3 minutes. 225 ÷ 3 = 75 beats per minute.

Jordy's heart beat 360 times in 5 minutes. 360 ÷ 5 = 72 beats per minute.

So your answer is B. Monica had the faster heart rate of 75 beats per minute.

Hope this helps. :)
