Question

A 208-yard-long road is divided into 16 parts of equal length. Mr.Ward paints a 4-yard-long strip in each part. How long is the unpainted strip of each part of the road?

Answer 1

In each part, unpainted strip is 9 yard long.

Explanation:

The total strip is of given length 208 yard long.

It is divided into 16 parts, so the length of each strip is,

`= (208)/(16) = 13` yard .

Now it is given that, Mr.Ward paints a 4-yard-long strip in each part,

so the unpainted part of strip length is given by,

`13 - 4 = 9` yard.

Thus, the unpainted part of strip is 9 yard long.

Answer 2

Length of unpainted strip of each part of the road = 9 yard

Explanation:

Total length of the road = 208 yard

When it is divided into 16 equal parts,

length of each part =
`(208)/(16)`

= 13 yard

Mr.Ward paints 4 yard long strips in each part .That is he does not completely paint the part but paints only a small section of each part.

Length of unpainted strip of each part of the road = length of each strip - length of strip painted by Mr.Ward

Length of unpainted strip of each part of the road = 13 - 4

Length of unpainted strip of each part of the road = 9 yard
