Answer:
385 miles
Step-by-step explanation:
Let's start by finding the unit rate (how far she can drive in 1 hour):
[tex]\frac{165mi}{3hr}[/tex]
Divide both the numerator and the denominator by 3 hours (Please note that this is essentially dividing the fraction by 1, so we are only simplifying the fraction, not changing it):
[tex]55mi/hr[/tex]
Now, using a unit converter, we can find out far she can drive in 7 hours:
[tex]7hr(\frac{55mi}{1hr})=7*55mi=385mi[/tex]
She can drive 385 miles in 7 hours
