    One whole breath is when the person breathes in and breathes out. This is is from O to C. From 0 to C it takes 5 seconds. You want to find out breathing rate per minute. A minute is 60 seconds. So you want to find out how many breathes are in a minute given 1 breath is 5 seconds and you want to find out how many are in 60 seconds, you just divide 60/5 and thats the answer.

    Hopefully I explained that well enough..
