Callie and Gellen have equivalent heart rates.

Step-by-step explanation:

Hi, to solve this problem we have to calculate each beat per second of each individual.

So:

Aaron 166 times in 120 seconds: 166/120: 1.30 beat per second

Callie  88 times in 60 seconds: 88/60: 1.46 beat per second

Amma 48 times in 30 seconds: 48/30: 1.6 beat per second

Galen 22 times in 15 seconds: 22/15: 1.46 beat per second

Callie and Gellen have the same results.

So, Aaron and Gellen have equivalent heart rates.
