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.
