Answer:

3.29ft/mi

Explanation:

The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.

 Mathematically;

  River gradient = \frac{Elevation}{horizontal distance}  

 Elevation  = 1229ft

Horizontal distance  = 373miles

  River gradient  = \frac{1229}{373}   = 3.29ft/mi
