For this case, the unit rate is given by:
[tex]r = \frac{d}{t}[/tex]
Where,
d: distance traveled
t: time to travel the distance
Substituting values we have:
[tex]r = \frac{2884}{7}[/tex]
Doing the calculation we have:
[tex]r = 412[/tex]
Answer:
the average thousand she traveled per day during the trip is:
[tex]r = 412[/tex]
