When does a 600-calorie meal exceed the number of calories burned in two hours? when a 200 lb person plays basketball when a 160 lb person does aerobics when a 200 lb person walks at 3.5 miles per hour when a 160 lb person plays volleyball

The answer is "when a 200 lb person plays basketball"

For a 200 pound person, the amount of calorie burned in an hour by playing basketball is already 728 according to Ainsworth BE. So doing this in 2 hours would increase the amount of calories burned in total of 1456 (728 kcal * 2 hours) which already exceed the 600 calorie gained from the meal.
