total work done by heart in one minute ( 60 seconds)= power*time= 2.5*60=150J
work done in each beat=1.5 J
then the no. of beats= work done in one min/work done in one beat= 150 J/1.5 J= 100 times
work done in each beat=1.5 J
then the no. of beats= work done in one min/work done in one beat= 150 J/1.5 J= 100 times
