You can put this solution on YOUR website!
70 beats for 1 minute is the same as x beats for 10 seconds.
\n" ); document.write( "You need to make sure you use the same time units (seconds and seconds or minutes and minutes).
\n" ); document.write( "70 beats for 60 seconds is the same as x beats for 10 seconds.
\n" ); document.write( "Mathematically, that is,
\n" ); document.write( " $\"70%2F60=x%2F10\"$
\n" ); document.write( " $\"x=700%2F60\"$
\n" ); document.write( " $\"x=11.7\"$
\n" ); document.write( "Use the integer values around the exact answer.
\n" ); document.write( "The number of beats in 10 seconds should be between 11 and 12 Beats. \n" ); document.write( "
