which means x = 51°

ANEK [815]
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:


\frac{1}{6} *x

We also know how big it is:

\frac{1}{6} *x= \frac{1}{1 500}

now, let's multiply both sides by 6:
\frac{6}{6} *x= \frac{6}{1 500}
1 *x= \frac{3}{750}
x= \frac{1}{250}


So the answer is that it would be x= \frac{1}{250} miles wide
