Question

Susanne checks her heart rate for six seconds, she counts 13 beats. Roughly, how many beats will she have in a minute

Answer 1

Susanne will have about 130 heartbeats in one minute.

Explanation:

You can look at this problem as 13 beats/6 seconds = x beats/60 seconds. This means that you can make the denominators equal by multiplying both numerator and denominator by 10. 6 x 10 = 60 and 13 x 10 = 130. This means that x would equal 130 so there are 130 beats in one minute.
