Question

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing strip must be 1/6 of a mile long. With the amount of material that has , what is the greatest possible width the land strip, in miles?

Answer 1

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:



`(1)/(6) *x`

We also know how big it is:


`(1)/(6) *x= (1)/(1 500)`

now, let's multiply both sides by 6:

`(6)/(6) *x= (6)/(1 500)`

`1 *x= (3)/(750)`

`x= (1)/(250)`


So the answer is that it would be
`x= (1)/(250)` miles wide
