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

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

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
