Am I doing this correctly and is the answer right?
Assuming 1 hour of running in plsce burns 650 cal/h if a person ran in place for 15 min.'s how many calories would be burned?
650/1 * 1/4= 325/2=162.5 calories burned every 15 min.'s
650/1 = x/.25
will give the same answer.
Reading it would be 650 is to one hour as x is to .25 hr
Yes, you are on the right track with your calculations. To find out how many calories would be burned in 15 minutes of running in place, you can use the information that 1 hour of running in place burns 650 calories/hour.
To solve it, you can set up a proportion.
1 hour is to 650 calories as 15 minutes is to x calories.
To convert 15 minutes to hours, divide it by 60: 15 minutes / 60 minutes = 0.25 hours.
So now you have the proportion:
1 hour / 650 calories = 0.25 hours / x calories.
You can cross-multiply and solve for x:
1 * x = 650 * 0.25
x = 162.5 calories.
Therefore, the answer is correct. Running in place for 15 minutes would burn approximately 162.5 calories.
