Answer:

394.67 minutes (or about 6.58 hours)

Step-by-step explanation:

<u>For 145.8 feet long fence:</u>

At a rate of 2.25 feet per minute, its gonna take him

\frac{145.8}{2.25}=64.8  minutes to pain

Also

At a rate of 0.75 feet per minute, its gonna take him

\frac{145.8}{0.75}=194.4  minutes to stain

<u>For 76.2 feet long fence:</u>

At a rate of 2.25 feet per minute, its going to take him

\frac{76.2}{2.25}=33.87  minutes to pain

At a rate of 0.75 feet per minute, its gonna take him

\frac{76.2}{0.75}=101.6  minutes to stain

In total, it's gonna take him:

64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes

In hours, that is 394.67/60 = 6.58 hours
