Answer:
47.06%
Explanation:
First, let's calculate the number of miles that Hannah has driven. So:
680 miles - 360 miles = 320 miles
Now, to know what percent represents 320 miles, we need to divide this quantity by the total number of miles and then multiply by 100, so:
[tex]\frac{320}{680}\times100=0.4706\times100=47.06\text{ \%}[/tex]Therefore, she has driven 47.06% of the trip.
