Question

You answer should say: Car _ by __ km/hr (Use care in answering!)

Answer 1

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
