17 Three boys A B and C decide to walk on straight tracks parallel to a power line in which poles are 18 m apart Boys A and B walk on the same track while C on a different track in the same direction with velocities 4 m s 2 m s and 2 m s respectively The track of boys A and B is equidistant from the power line and from the track of the boy C In the beginning all the boys and one of the poles are in a line that is perpendicular to the power line Draw a graph to show how does number of poles that the boy C can see through the space between boys A and B vary with time Track of boy A and B Track of boy C
