Answer:
144 minutes
Step-by-step explanation:
1 hr = 60 minutes
5/12 of a fence in 60 mimnnutes
(5/12)x = 60
Multiply both sides by 12/5
x = 60 * 12/5
x = 144
144 minutes
If Archibald and Rasmus can paint the equivalent of 5/12 of a fence in an hour, then 144 minutes will take them to complete the job.
What is an algebraic expression?
An algebraic expression stands for the combination of variables, coefficient, constant, or all three in a mathematical form where both sides are set equivalent to each other.
Let x be the minutes.
1 hr = 60 minutes
5/12 of a fence in 60 minutes
(5/12)x = 60
Multiply both sides by 12, and we get
[tex]$12 \cdot \frac{5}{12} x=60 \cdot 12$[/tex]
Simplifying the above equation, we get
5x = 720
Divide both sides by 5
[tex]$\frac{5 x}{5} = \frac{720}{5}[/tex]
Simplify
x = 144
The value of x = 144.
Therefore, 144 minutes will take them to complete the job.
