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.
For example, an 185-lb person who walks 30 minutes at 3.5 mph burns about 175 calories whereas a 125-lb person does the same burns about 125 calories only. The below-given chart indicates how many calories burned walking for an hour according to the body weight the person and speed of walking a mile per hour.
