expeople1 [14]

Answer:

GT, GV, PT, PV, ET, and EV.

Step-by-step explanation:

Given that

The number of topics Travis has to chose from are 3 topics(G, P, E).

The number of ways Travis can study each topic are 2 ways(T, V).

Essentially, the number of combinations Travis is expected to be able to chose from is given as

The number of combinations = The number of topics * The number of ways

The number of combinations = 3 * 2

The number of combinations = 6

Therefore, the total possible combinations has to be

disa [49]

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

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