satela [25.4K]

<h3><u>Answer:</u></h3>

Average of salary of Anne and David is 1.25 of Peter's Salary

<h3><u>Explanation:</u></h3>

In the question, relations between salaries of Peter, Anne, and David is given. From the given relations, we need to make few equations and calculate the average of Anne and David in terms of Peter's Salary.

Let us assume Peter's Salary as P.

Then we can calculate Anne's salary A = $\frac{P}{2}$ .

Also David's salary = D = $2 \times P$

Average of Anne's and David's salary = $\frac{A+D}{2}$

Average of Anne's and David's salary = $\frac{\frac{P}{2} + 2 \times P}{2}$

Average of Anne's and David's salary = $\frac{5 \times P}{4}$

Average = 1.25 \times P

on a lake, Carol rowed a boat for 1/8 mile. Then luke rowed the boat for 3/8 mile. how far did carol and like row in all? simpli

Semmy [17]

Answer:

$Total = \frac{1}{2}$

Step-by-step explanation:

Given

$Carol = \frac{1}{8}$

$Luke = \frac{3}{8}$

Required

How far did they row together

To do this, we simply add the distance they both covered.

$Total = Carol + Luke$

This gives;

$Total = \frac{1}{8} + \frac{3}{8}$

Take LCM

$Total = \frac{1+3}{8}$

$Total = \frac{4}{8}$

Simplify

$Total = \frac{1}{2}$

<em>Hence, they both rowed 1/2 mile</em>
