Answer 1

Part 1: The right answer is Option B.

Part 2: The right answer is Option B.

Step-by-step explanation:

Given,

1 hour = 120 calories

Part 1: How many calories are burned per minute when walking on a treadmill?

1 hour = 120 calories

1 hour = 60 minutes

Therefore,

60 minutes = 120 calories

1 minute = $\frac{120}{60}=2\ calories$

2 calories are burned per minute.

The right answer is Option B.

Part 2: Assuming you walk at a constant rate and burn 120 calories per hour, how many minutes will it take to burn 75 calories.

From part 1;

1 minute = 2 calories

1 calorie = $\frac{1}{2}\ minute = 0.5\ minutes$

75 calories = 75*0.5 = 37.5 minutes

The right answer is Option B.
