Question

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?

Answer 1

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.
