Astream begins at an elevation of 200 meters and flows a distance of 400 kilometers to the ocean? what is the average gradient?

The average gradient is

Step-by-step explanation:

We have two important data to solve this problem:

1- Stream begins at an elevation (y) of 200 m

2- Stream flows a distance of (x) 400 km.

We need to calculate the average gradient. Gradient definition is the drop in elevation of a stream divided by the distance the water travel.

So, gradient (g) will be elevation (y) divided by distance (x).

Finally, the average gradient is .

5/12, or 5: 12

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
