Final answer:
The lowest point in Egypt is the Quattara Depression, which is 4/5 miles below sea level. The highest point is Mount Catherine, which is 6/8 miles above sea level. The difference between the lowest and highest points is -0.05 miles or 1 mile.
Step-by-step explanation:
The lowest point in Egypt is the Quattara Depression, which is 4/5 miles below sea level. The highest point is Mount Catherine, which is 6/8 miles above sea level. To find the difference between the lowest and highest points, we need to subtract the lowest point from the highest point.
Highest point - Lowest point = Mount Catherine - Quattara Depression
= 6/8 miles - (4/5 miles) = (30/40 miles) - (32/40 miles) = -2/40 miles = -1/20 miles
So, the difference between the lowest and highest points in Egypt is -1/20 miles or -0.05 miles. Therefore, the answer is d) 1 mile.
