Respuesta :
The average gradient of the stream is 3.5m/km
The elevation of the stream = 1000 meters
The elevation of the lake = 300 meters
The distance of the lake from the source = 200 km
The formula for the average gradient =
[tex]Gradient=\frac{change invalue}{change in distance}[/tex]
Change in value = 1000m - 300m
= 700m
Change in distance = 200km
[tex]Gradient=\frac{700}{200} =3.5m/km[/tex]
In conclusion the average gradient of this stream is 3.5m/km
