Question

A stream begins at an elevation of 500 meters above sea level and flows over a distance of 200 kilometers to the ocean. What is the average gradient?

Answer 1

`2.5\ m/Km`

Step-by-step explanation:

given,

elevation of the stream = 500 m

distance of the ocean = 200 Kilometer

average gradient = ?

gradient is the increase in height of the flow with respect to the horizontal distance traveled.

gradient =
`(500\ m)/(200\ km)`

gradient =
`2.5\ m/Km`

Hence, the average gradient of the stream is equal to
`2.5\ m/Km`
