Based on a chart, who would burn the most calories in 30 minutes?

To determine which activity would allow Betty to burn the most calories in 30 minutes, it's essential to consider the intensity and nature of each activity listed. Running is generally known to be one of the highest-calorie-burning activities due to its vigorous intensity. When evaluating Betty's activities, running would typically result in a higher calorie expenditure compared to walking, dancing, or playing golf.

Walking a 10K in 90 minutes implies a steady pace that would likely lead to a considerable energy expenditure, especially if the distance is covered at a brisk pace. In contrast, dancing can vary in intensity but can often be less intense than running. Playing golf, although it can involve walking the course, often includes periods of rest while waiting and is typically less physically demanding.

Thus, the answer chosen indicates that walking a 10K in that timeframe allows for a sustained aerobic exercise level that would likely result in a higher overall calorie burn compared to the other activities mentioned, balancing duration and intensity effectively.
