Answer:

The stream gradient = 5 feet/miles

Explanation:

Steam gradient formula is =  

the difference in elevation between two points on the stream over the  

distance along the stream which is measured in feet/mile, inch / km etc.

The change in stream elevation- 10 feet.  

The stream distance (shown in the map)- 2 miles  

Therefore, stream gradient- Change in stream elevation/stream distance  

The Stream gradient= 10 feet/ 2miles= 5 feet/miles.
