Derived Measurments Extended Reponse
Marks heart beats 16 times in 15 seconds. At that rate, how many times will it beat in one minute? Be sure to include the appropiate unit.
Marks heart beat would be 64 beats/minute because if you start with 16 beats per 15 minutes you will have to multiply 16 and 15 by 2,3, and 4. Like this: 15 by 2, 15 by 3, 15 by 4 which equals 60 and that equals to 1 minute. You would do 16 the same way 16 by 2, 16 by 3, 16 by 4 which equals to 64. So if his heart beat keeps beating 16 beats per 15 minutes the answer would be 64 beats in one minute.
