The number of calories you burn depends on your weight. A 140-pound person burns 225 calories during 30 minutes of jogging. Find the number of calories that a 230-pound person would burn during the same activity, assume they burn calories at the same rate.

If one person weighs 150 pounds (68 kg) and another person weighs 200 pounds (91 kg) and they both cycle for 30 minutes, the 200 pound person will burn more calories than the 150 pound person. That is true for all activities; the larger your body size the higher number of calories you will burn.
