Question

When a river flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flows horizontally find the slope of the river shown to the right. 81ft width 384 is the length

Answer 1

The slope can be calculated as:
Slope = rise / run

The width is the rise, the length is the run
Slope = 81 / 384
Slope = 0.21

Answer 2

The slope of the river is 0.210 ft.

Explanation:

Given : When a river flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flows horizontally, 81 ft width 384 is the length.

To find : The slope of the river?

Solution :

Slope is defined as how many units we move along the y-axis when we move along the x-axis.

We have given length i.e. horizontal distance or x-axis of the river is 384 ft.

and width i.e. vertical distance or y-axis of the river is 81 ft.

By definition of slope,

`\text{Slope}=\frac{\text{Vertical distance}}{\text{Horizontal distance}}`

`\text{Slope}=(81)/(384)`

`\text{Slope}=0.210`

Therefore, The slope of the river is 0.210 ft.
