| **The slope of the Dnieper River is 11 cm / km, the length is 2285 km. Determine at what altitude above sea level the Dnieper River originates, that is, determine the height of the source of the Dnieper River.**

The slope of a river is the ratio of its fall (in cm) to its length (in km).

U (river slope) = (source – mouth): L (river length), hence

hflow = Y × L – hmouth = 11 cm / km × 2285 km – 0 m = 25135 cm = 251, 35 m.

Answer: the source of the Dnieper River is located at a height of 251 m and 35 cm.
