Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel. How long would i
Whitepunk [10]

Answer:

32 hours.

Step-by-step explanation:

Let x represent the time taken by Russell and Aaron to build the shed.

We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.

Russell's work rate would be \frac{1}{x}.

Since Aaron works three times as fast as Russel, so Aaron's work rate would be \frac{3}{x}.

Part of work done by in one hour would be \frac{1}{8}.

We can represent our given information in an equation as:

\frac{1}{x}+\frac{3}{x}=\frac{1}{8}

Let us solve for x.

\frac{1}{x}*8x+\frac{3}{x}*8x=\frac{1}{8}*8x

8+3*8=x

8+24=x

32=x

Therefore, it will take Russell 32 hours to build the shed working alone.

The angles of a quadrilateral add to 360, so we can solve for x by adding the 4 angle measures together and setting it equal to 360:

90 + 140 + (x - 10) + (x - 20) = 360

Combine like terms:

230 + 2x - 30 = 360

200 + 2x = 360

200 - (200) + 2x = 360 - (200)

2x = 160

Divide both sides by 2:

2x/(2) = 160/(2)

x = 80
