Question

On a 1/5 scale drawing of a car, one part is 8 inches long. How long will the actual car part be?

Answer 1

The actual length of the given car part is 40 inches.

Explanation:

Given : Scale of drawing of a car is
`(1)/(5)`

Also, given one part is 8 inches long.

We have to find the actual length of the given car part.

Since, the given scale decreases the actual length by a factor of
`(1)/(5)`

So, The actual length will be

New length =
`(1)/(5)` × actual length

Thus, Actual length will be

Actual length = 5 × new length

Actual length = 5 × 8 = 40 inches.

So, The actual length of the given car part is 40 inches.

Answer 2

If it's one fifth scale, take it times five to get the whole scale. 8 times five equals 40. The car is 40" long, 3' 4" long, or three and one third feet long.
