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.
The calories-per-mile rule of thumb changes slightly for walking. A study done by researchers at Syracuse found that men burned about 105 kilocalories/mile on average running a mile in 9 minutes and 30 seconds, and about 52 calories when walking the same mile in 19 minutes. For the women in the study, that burn was 91 and 43 calories, respectively.
