S = (n-2) * 180
s = (14-2) * 180
s = 2160
2160/ 14 = 154.3
The answer is A
Answer:

Step-by-step explanation:
Answer:
Car B by 20km/hr
Step-by-step explanation:
well, we first calculate the speeds of both cars. there is an allocated dot along the 6 hour mark for the line graph of both cars. hence, using a time of 6 hours, we use their respective distances to produce an answer. car a has travelled 360 km while car v has travelled 480 km.
hence:
speed of car b = 480/6 = 80
speed of car a = 360/6 = 60
