The angles get added.
Let <em>z</em> = <em>r</em> exp(<em>i</em> <em>θ</em>) and <em>w</em> = <em>s</em> exp(<em>i</em> <em>φ</em>). Then
<em>zw</em> = <em>rs</em> exp(<em>i</em> <em>θ</em>) exp(<em>i</em> <em>φ</em>) = <em>rs</em> exp(<em>i</em> (<em>θ</em> + <em>φ</em>))
Answer:
6.5 miles per hour
Step-by-step explanation:
At first, Jim was paddling against the current for 3 hours. Then, he paddled for 1 hour with the help of the current.
Let x be Jim's rate without the current and y be the rate of the current:
By solving the linear system, we can find the rate of the current y:
The current has a rate of 6.5 miles per hour.
