m 1. A river is 12.2 m wide with an average depth of 5.1 m. The river is flowing at a speed of 1.7 At one point in the river, there is a section of rapids. Here, the speed of the water increases to a. -3.6 . What is the effective area of the river at this point? b. Later, the river dumps into a lake where the area rapidly increases to 202 m2. How fast is the water moving just after it enters the lake?

### Problem 1
A river is 12.2 m wide with an average depth of 5.1 m. The river is flowing at a speed of \(1.7 \, \frac{m}{s}\).
a. At one point in the river, there is a section of rapids. Here, the speed of the water increases to \(3.6 \, \frac{m}{s}\). What is the effective area of the river at this point?
b. Later, the river dumps into a lake where the area rapidly increases to \(202 \, m^2\). How fast is the water moving just after it enters the lake?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faa38d3af-d2a1-4c36-a58b-a982b5534c39%2F8c400c8a-4ab1-46b3-bb1b-ba2c42dc178b%2F5qiu09c.jpeg&w=3840&q=75)
