Ancient Nubia occupied the territory beyond, or upriver, the first cataract while Ancient Egypt occupied the lands below, or downriver, of the first cataract. Historians have come to divide Nubia itself into sub regions with Lower Nubia comprising the lands between the first and second cataract and Upper Nubia being the regions beyond the second cataract.
How You Burn Calories. Your weight x distance = energy used walking. Time does not matter as much as distance. If you speed up to walking a mile in 13 minutes or less, you will be burning more calories per mile. But for most beginning walkers, it is best to increase the distance before working on speed. A simple rule of thumb is 100 calories per mile for a 180 pound person.
Your weight and the distance you walk are the biggest factors in how many calories you burn while walking. A rule of thumb is that about 100 calories per mile are burned for an 180-pound person and 65 calories per mile are burned for a 120-pound person. Your walking speed matters less.
