Q.

20

. Tim takes his pulse for

10 \mathrm{sec}

and counts

12

beats. How many beats per minute is this?

Find Beats per Minute: We need to find out how many beats happen in a minute. There are $60$ seconds in a minute, so we need to multiply the number of beats in $10$ seconds by $6$ to get the number of beats in $60$ seconds. $\newline$ Calculation: $12$ beats $\times 6 = 72$ beats per minute.
