Courtney burns 180 calories per 30 minutes of hiking.
Complete the table to chart her calorie expenditure for different amounts of time.
Time(minutes) 30 10 5 20 75 45
Calories Burned _ _ _ _ _ _
1.How many calories will Courtney burn if she hikes for 1 hour?
2.How many minutes would she have to hike to burn 240 calories?
3.How many calories can she burn if she hikes for 105 minutes?
For #1, it would just be double of how much Courtney burns in 30 minutes (so 180*2=360)
For #2, determine the unit rate (so 180/30=6/1), then make the proportion 6/1=240/x and solve. You'll get 40 minutes when solved.
For #3, it's the same thing as #2, make the proportion 6/1=x/105 and solve. You'll get 630 calories when solved.
Hope this makes sense.
Just remember what I showed you for the 3 problems and you can apply that same method when filling out the chart.
Anytime!
You're welcome. Oh, I forgot about the chart, but I think you can do that on your own.
thanks
For the chart part, just multiply each number by 6 and you'll get the answer. If not sorry ;)
I dot get it tho
Can someone plz fill out the chart!!!!!!!!
To complete the table, we can calculate Courtney's calorie expenditure for different amounts of time based on the given information.
1. To find out how many calories Courtney will burn if she hikes for 1 hour (60 minutes), we can divide the time by 30 minutes (the time it takes to burn 180 calories).
60 minutes ÷ 30 minutes = 2
So, Courtney will burn 180 calories per 30 minutes multiplied by 2, which gives us:
180 calories × 2 = 360 calories
Therefore, Courtney will burn 360 calories if she hikes for 1 hour.
2. To determine how many minutes Courtney would have to hike to burn 240 calories, we need to divide the desired calorie burn by the calorie expenditure per 30 minutes.
Desired calorie burn ÷ Calories burned per 30 minutes = Minutes required
240 calories ÷ 180 calories = 1.33
So, Courtney would have to hike for approximately 1.33 * 30 minutes to reach 240 calories, which is equal to 39.9 minutes.
Therefore, she would have to hike for approximately 40 minutes to burn 240 calories.
3. To calculate how many calories Courtney can burn if she hikes for 105 minutes, we divide the total time by 30 minutes (the time taken to burn 180 calories) and multiply the result by the calorie expenditure per 30 minutes.
105 minutes ÷ 30 minutes = 3.5
So, Courtney will burn 180 calories for every 30 minutes multiplied by 3.5:
180 calories × 3.5 = 630 calories
Therefore, Courtney can burn 630 calories if she hikes for 105 minutes.
