Question

number of hours spent walking
which statement is true?
a. at 0 hours, 120 calories are burned.

b. the point (1, 120) represents walking burns calories at a rate of 120 calories per

c. to burn 120 calories, an individual must walk for 2 hours.

d. an individual that walks for

Explanation:

Step1: Analyze Option A

At 0 hours (no walking), typically 0 calories are burned, so A is false.

Step2: Analyze Option B

The point \((1, 120)\) means in 1 hour, 120 calories are burned, so the rate is 120 calories per hour. This makes sense.

Step3: Analyze Option C

If rate is 120 cal/hour, to burn 120 calories, time should be \( \frac{120}{120}=1 \) hour, not 2. So C is false.

Step4: Analyze Option D (Partially Visible)

Assuming it's about 5 hours, with rate 120 cal/hour, calories burned would be \( 5\times120 = 600 \), but since the option is cut, but from other options, B is valid.

Answer:

B. The point (1, 120) represents walking burns calories at a rate of 120 calories per hour
