Answer:

4.5 miles

Step-by-step explanation:

Hello!

Let's take note the conversion factor of 1 mile=1760 yards.

We can use this relation to make a proportionality rule.

We don't KNOW the milage of James, but we know how many yards he ran.

[tex]\frac{1~mile}{1760~yards} = \frac{x~miles}{7920~yards}[/tex]

We can cross multiply to figure out x, the miles he ran.

(1)(7920)=1760(x)

7920=1760x

4.5=x

James ran 4.5 miles every week.
