The lowest point in Egypt is Quattara Depression at 4/5 miles below sea level. The highest point in the country is Mount Catherine at 6/8 miles above sea level. Determine the difference between the lowest point and highest point in Egypt.

31/20 miles

Step-by-step explanation:

Given that:

Lowest point = 4/5 miles below sea level

Highest point = 6/8 miles above sea level

Difference between lowest and highest point :

Point below sea level are represented as negative ; Hence, lowest point = - 4/5 miles

Highest point = 6/8 miles

Difference between lowest and highest point :

6/8 miles - (-4/5) miles

(6/8 + 4/5) miles

= (30 + 32) = 62/40 miles = 31/20 miles
