Sarah can paint 2 square feet of fence in 10 minutes .Fill in the missing parts to tell how long it will take him to paint a fen

Kitty [74]

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 = $6\times25 = 150ft^2$

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. = $\frac{150\times10}{2} = 750\ mins$

Now we know 1 hour = 60 mins.

Number of hours = 750 mins

Again By using Unitary method we get;

Number of hours = $\frac{750}{60} =12.5$

Hence Sarah will be able to paint 150 square feet of fence in 12 hours and 50 mins.
