Rosa is finding the number of yards in a kilometer.

Answer 1

Answer: Rosa is finding the number of kilometers in a mile.

Explanation:

According to the given information, we have:

1,760 yd=1 mi

0.914 m=1 yd

1 km=1,000 m

So, as we can see, Rosa wants to convert miles to yards, then yards to meters and finally meters to kilometers:

`(1 mi(1,760 yd)/(1 mi))( (0.914 m)/(1 yd))( (1 km)/(1,000 m))=1.608 km`

Then:

`1  mi=1.608 km` This is the number of kilometers in a mile.
