Answer:

Option D. 9 mi/hr downstream, 6 mi/hr upstream

Step-by-step explanation:

The complete question is

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way

Define the variables

Let

x -----> Alicia's rowing rate downstream in miles per hour

y ----> Alicia's rowing rate upstream in miles per hour

we know that

The rate is equal to the distance divided by the time

The time is equal to the distance divided by the rate

we have

$\frac{6}{x}=\frac{4}{y}$

$4x=6y$

$x=1.5y$ -----> equation A

$x=y+3$ ----> equation B

equate equation A and equation B

$1.5y=y+3$

$1.5y-y=3$

$0.5y=3$

$y=6$

Find the value of x

$x=1.5(6)=9$

therefore

Alicia's rowing rate downstream is 9 mi/h

Alicia's rowing rate upstream is 6 mi/h

Eccentric
Being eccentric can be likewise called peculiarity is irregular or odd conduct with respect to a person. This conduct would commonly be seen as surprising or pointless, without being verifiably maladaptive. Whimsy is diverged from "ordinary" conduct, the almost general means by which people in the public eye tackle given issues and seek after specific needs in regular daily existence. Individuals who reliably show benevolently capricious conduct are marked as "erraticisms
