When Jacob is running, his heart beats 23 times in 10 seconds. What is Jacob's heart rate in beats per minute (bpm) while running? 135 bpm
136 bpm
137 bpm
138 bpm

138 bpm

Explanation:

A minute has 60 seconds. You have 23 beats in 10 seconds. You could do a simple multiplication by 6 to get to the 60 seconds you need or you could say:

23 beats .......... 10 seconds

x beats .......... 60 seconds

x = 138 bpm

I think you got the point. Desires time is 6 times larger, so is the number of beats.
