Question
In a river, the water will move the fastest approximately in the _______ and ___________.outside, just below the surfacemiddle, at the surfaceoutside, at the surfacemiddle, just below the surface
Solution
The water in a river will move the fastest approximately in the middle, just below the surface.
Here's why:
-
In the middle: Water in the middle of the river tends to move faster than at the edges. This is because friction with the river banks slows the water down at the edges.
-
Just below the surface: Water just below the surface tends to move faster than water at the very surface or deeper down. This is because surface water is slowed down by wind resistance, and deeper water is slowed down by friction with the river bed.
So, combining these two factors, the fastest water in a river is typically found in the middle and just below the surface.

Brandon is on one side of a river that is 5050 m wide and wants to reach a point 200200 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 22 m/s and run at 66 m/s.(We assume that the speed of the water is negligible compared with the speed at which Brandon swims.)(Use decimal notation. Give your answer to two decimal places.)
