Sabra went for a long hike and burned 845 calories in 3 1/4 hours. nelson decided to go for a bike ride. he burned 1,435 calories in 4 7/8 hours. who burned the most calories per hour?

Nelson burned the most calories per hour

Explanation:

To solve this question, we will get the amount calories burned by each in one hour and then compare the two values

To do this, we will divide the total amount of calories burned by the total time

1- For Sabra:

We are given that she burnt 845 calories in (which is equivalent to 3.25) hours

Therefore:

Calories burnt in an hour = calories/hour

2- For Nelson:

We are given that he burnt 1435 calories in (which is equivalent to 4.875) hours

Therefore:

Calories burnt in an hour = calories/hour

3- Comparing the two values:

From the above calculations, we can deduce that Nelson burned the most calories per hour

Hope this helps :)

b. f(x) = –√x + 3this is the correct answer
