A hamster’s heart beats about 450 times per minute. How many times would a hamster’s heart beat in 30 seconds?

This is a pretty simple math problem. We need to know this: ***1 minute = 60 seconds*** So, if a hamster's heart beats 450 times in 60 seconds, how many times will it beat in just 30 seconds? Remember, 30 is half of 60.
