Your Answer that you are looking for my young padawan is C

Answer 2

120

Explanation:

the bottom half of the number line are the minutes so if we are looking for the amount of heart beats in three minutes we have to find the 3 on the bottom of the number line.

Next we look at the top number. Those are heart beats per amount of minutes. Whichever number is on top of three is the amount of heartbeats in 3 minutes.
