Question 245645: Karen traveled almost 350 mi in under 7 h of highway driving. She stopped
for a brief rest that was not included in her driving time. Karen averaged 60 mi/h for
the first part of her trip and 50 mi/h for the second part of the trip. Write and graph
a system of inequalities that can be used to determine how many hours Karen spent

f + s = 7
50s + 60f = 350
-50s -50f = -350
50s + 60f = 350
10f = 0
0 + f = 7
f = 7
she spent 7 hours on the first part
and 0 hours on the second part
