Find the unit rate for each Olivia and Ryan:
2 2/5 km 15 36 km
------------ * ------- = ------------ = 3.6 km/hr (Olivia)
2/3 hr 15 10 hr
4 1/2 km 2 9 km
------------- * --------- = --------- = 3 km/hr (Ryan)
1 1/2 hr 2 3 hr
Olivia walked 0.6 km/hr faster than did Ryan.
Assuming that each of these letters are splitting this half and half (based off of the information given here) then AB would be 9.4
C. This is because the lines of the graphs can be seen using these. The inequality symbols in this case do not help you make the decision.
3(6)-1/2(6)+1 is the correct answer
