Step-by-step explanation:
you will first have to figure out how long she drove in one hour...
819/13 = 63
63 miles per hour
567/63 = hours to drive 567 miles = 9
Answer:
9 hours
Step-by-step explanation:
We can use a ratio to solve
819 miles 567 miles
-------------- = --------------
13 hours x hours

819 x = 567*13
Divide each side by 819
819x/819 = 567*13/819
x =9
