Henry is choosing between two exercise routines. in routine #1, he does only running, burning 15.5 calories per minute. in routine #2, he burns 22 calories walking. he then runs at a rate that burns 13.3 calories per minute. for what amounts of time spent running will routine #1 burn more calories than routine #2?

11 minutes

Step-by-step explanation:

So what I did above is that I used a table to calculate the calories burn for each minute. For example, let's say that Henry works out for 12 minutes using both routines

1 & 2 represents the Routines

1-12 represents the calories he burned per minute

(x represents calories burned per minute)

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
