Answer:
C is highest , A is Lowest
No
B = 12 km/Hr
Explanation:
Speed of Car A = (14 - 6)/(1.6-0) = 8/1.6 = 6 km/hr
Speed of Car B = (14 -0)/(1.4-0) = 10 km/Hr
Speed of Car C = (14 -2)/(1.0-0) = 12 km /hr
Car C has highsest Speed = 12 km/Hr
Car A has Lowest Speed = 6 km/hr
Car C is already ahead o A & B & also Fastest
so It would not meet CarA & CarB
=> These three cars Would not neet at the same point on the road
