Answer
4,320 beats/hr
103,680 beats/day
Work Step by Step
72 beats/min
To convert if to beats/hr we need to convert min to hours. There are 60 minutes in one hour so we multiply 72 x 60.
72 beats/min * 60 min/hr
***minute units cancel out
= 4,320 beats/hr
4,320 beats/hr
To convert if to beats/day we need to convert hours to days. There are 24 hours in one day so we multiply 432 x 24.
4,320 beats/hr * 24 hr/day
***hour units cancel out
= 103,680 beats/day
