Answer
Aiden’s method is incorrect because he divided the beats per minute by seconds without converting the time units. The correct approach is to convert 30 seconds to 0.5 minutes and multiply by 240 beats per minute, resulting in 120 beats in 30 seconds.

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!
