So, in order to find modesty Hot writ, it's per minute. We need to first find modesty, period between beats the time period between each beat, another to fire. How many beats there are in a minute. So what we're gonna do is we're gonna use the craft for the Ficker 20.342 point 34 So find the period. We look at the pics, right? So just a rough graph. Maybe have tea material. Blood pressure graph. Write something like that. What you want is to find a pick values between, uh and we only find the time difference between so 60 x axis is in terms. Off time. You're able to fine estimates. What is the distance between them? So this about this points about one point tree seconds. The other point here is what was your point? Six seconds? Richt. So the rough time time period between each hot Bt's about it's your 0.7 seconds and so we can find what ISS The total number beats in one minute 90 right? Be taking 60 seconds. Identifies 2.7 should give us about 86 beats. Perfect. It
