One-third cup of vanilla ice cream provides about 145kcal of energy. A typical adult uses about 195kcal/hr of energy while walking. If all of the enrgy in one third of a cup of valilla ice cream were to be burned off by walking, how many minutes would it ake for this energy to be used? How to set it up going from kcal to min burned
145kcal / 195kcal/hr = 0.74 hr or 45 minutes
To set up the calculation, you need to convert the energy in calories to the amount of time needed to burn off that energy. Here's how you can do it:
Step 1: Determine the energy in calories that needs to be burned off. In this case, it's 145 kcal.
Step 2: Determine the energy expenditure per hour. It is given that a typical adult uses about 195 kcal/hr while walking.
Step 3: Divide the energy needed to be burned off by the energy expenditure per hour to find the number of hours needed to burn off the ice cream's energy.
145 kcal ÷ 195 kcal/hr = 0.74 hours
Step 4: Convert hours to minutes by multiplying the result from step 3 by 60 (since there are 60 minutes in an hour).
0.74 hours × 60 minutes/hour = 44.4 minutes (rounded to the nearest minute)
Therefore, it would take approximately 44 minutes and 24 seconds (rounded to the nearest minute) to burn off the energy provided by one-third cup of vanilla ice cream while walking.
