The speed of the car = distance/time
Let us find the speed of each car
Car A starts from (0, 0) to (6, 360)
Its speed is
[tex]SA=\frac{360-0}{6-0}=\frac{360}{6}=60[/tex]The speed of car A is 60 km/h
car B starts at (1, 0) to (6, 480)
Its speed is
[tex]SB=\frac{480-0}{6-1}=\frac{480}{5}=96[/tex]The speed of car B is 96 km/h
Therefor car B is faster than car A
Since the difference between their speeds = 96 - 60 = 36 km/h
Car B is faster by 36 km/h
