A 170 pound person burns 252 calories during 30 minutes of tennis,find the number of calories a 210 pound person would burn during the same activity.
210/170 = x/252
Solve for x.
To find the number of calories a 210 pound person would burn during 30 minutes of tennis, we can use a proportional relationship.
First, let's establish the proportion between weight and calories burned:
Weight (in pounds) : Calories burned (in 30 minutes)
170 : 252
210 : ?
To find the missing value, we can set up a proportion and solve for the calories burned for a 210 pound person:
170/252 = 210/x
To solve for x (the calories burned for a 210 pound person), we can cross multiply:
170x = 210 * 252
Next, divide both sides of the equation by 170 to solve for x:
x = (210 * 252) / 170
Using a calculator, we can simplify the equation:
x ≈ 311.76
Therefore, a 210 pound person would burn approximately 312 calories during 30 minutes of tennis.
