please tell the answer I will mark as brainlist​

5 Km and car b is moving fater

Answer:

Explanation:

(1) as marked on the graph when t=0 the distance between A and B is 50km

therefore A is 50 km ahead of B

(2) as the graph is a straight line it isevident that A and B moves in a uniform speed/velocity

this can be calculated by the gradient of the graph

Gradient= Difference of y coordintes/ Difference of x coordinates

for A

gradient= 15-5/3-0 = 10/3ms-1

for B

gradient=20-0/3-0 = 20/3ms-1

therefore B moves with a higher velocity

(3) In a displacement time graph when two curves intersect each other this means they both meet each other at that time interval According to this graph the two lines intersect at 1.5h therefore after 1.5h and at 10 km a and B meet each other
