Please please please answer this question for me THANK YOU!!! 40 POINTS

Step-by-step explanation:

The vertical axis represents distance traveled, and the horizontal axis represents time.

At the beginning, time = t = 0 and distance = d = 0.

Between t = 0 and t = 20, the group moved in the positive direction by 40 units.  Then, between t = 20 and t = 60, they stayed where they were, at distance 40 units from the origin.  (Slope of graph is zero; this means the rate of travel is zero.)

Between t = 60 and t = 120, the group moves further away from the origin (actually, further away from Point C, reaching Point D, which is 150 units from the origin.  

Between t = 120 and t = 160, the group is at rest / does not move.

Between t = 160 and t = 200, the group moves back to the origin (distance = 0) at a steady rate.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
