A drink has 450 calories. How long would a 100 lb person have to walk to burn these calories. Walking burns 162 calories per 3 hours

Question

this is on a worksheet and i don't know how to solve even though it is probably very easy math

Answer 1

You know it takes 3 hours to burn 162 calories, and you want to burn 450 calories. So,

 

(450 calories/162calories) = (X hours/ 3 hours)

 

Solve for X:

X = (450/162) * 3 =8.33 Hours

 

Another way to look at it is this:

 

162 Calories/3 hours = 450 Calories/X Hours

It comes out to the same thing.
