Answer:
Sarah will be able to paint 150 square feet of fence in 12 hours and 50 mins.
Step-by-step explanation:
Given:
Width of the fence = 6 feet
Length of the fence = 25 feet
Now we will first find the Area of the fence we get;
Area of the fence is length times width.
framing in equation form we get;
Area of the fence = [tex]6\times25 = 150ft^2[/tex]
Now Given:
2 square feet fence painting = 10 mins
so 150 square feet fence painting = number of mins require to paint 150 square feet fence.
By using Unitary method we get;
number of mins require to paint 150 square feet fence. =[tex]\frac{150\times10}{2} = 750\ mins[/tex]
Now we know 1 hour = 60 mins.
Number of hours = 750 mins
Again By using Unitary method we get;
Number of hours = [tex]\frac{750}{60} =12.5[/tex]
Hence Sarah will be able to paint 150 square feet of fence in 12 hours and 50 mins.
