16. A kitten's heartbeat can be as fast as 240 beats per minute. To find the number of times a kitten's heart beats in 30 seconds, Aiden says divide 240 by 30 . Do you agree with him? Why or why not?

I don't agree with Aiden's approach! To find the number of heartbeats in 30 seconds, you should first calculate how many beats occur in one second. Since the heartbeat can be as fast as 240 beats per minute, divide that number by 60 seconds, resulting in 4 beats per second. Then, multiply 4 beats by 30 seconds to find that a kitten’s heart beats 120 times in half a minute. Easy peasy! Many people often overlook the fact that when working with time and rates, it’s essential to consider the appropriate units. Common mistakes include mixing up seconds and minutes or failing to account for the entire time frame involved. Just remember, units matter when you're crunching numbers!
