Question

Cherise is doing a 20-mile bike ride. In 1/3 min her heart beats 56 times. How many times does her heart beat per minute?

Answer 1

To find Cherise's heart rate in beats per minute (bpm), we can start with the information given: her heart beats 56 times in \( \frac{1}{3} \) of a minute.

To find out how many beats she has in a full minute, we can multiply the number of beats in \( \frac{1}{3} \) of a minute by 3:

\[
\text{Beats per minute} = 56 \text{ beats} \times 3
\]

Calculating this gives:

\[
56 \times 3 = 168 \text{ beats per minute}
\]

Therefore, Cherise's heart beats **168 times per minute**.
