Solution :

a. The slope for position time graph gives the velocity <br> Slope of line A=velocity of car `A` <br> `=(14-6)/(1.6-0) =(8)/(1.6) =5 km h^(-1)` <br> Slope of line B= velpcoty of car `B=(14-6)/(1.4-0) =10 km h^(-1)` <br> Slopl of line =velovity of car `C=(14-4)/(1-0) =12 km h^(-1)` <br> Hence car `C` has hieghest speed and car `A` has lowest speed. b. As clear form graph, the position of all three cars are bot same at any time, Hence the three cars never at the same point on the road. <br> c. From graph it is clear car `B` is apprximately `6 km` from the origin. <br> d. From graph car `A` travels berweenthe time it palled cars `B` and `C=1.2-0.6-0.6 h` <br> e. Relative velocity of car `C` with respect to car `A`, <br> `vec v,_(a)=vec v_(c)- vec v_(A) =12-=7 km h^(-1)` <br> f. Relative velocity of car `B` with respect to car `C` <br> ` vec v_(B,C)= vecv _(B)- vec_(C)=0 -12 =-2 km h^(2)`.
