25. A large number of pedestrians are walking in the same direction in queues on each side of a road of width b = 3.0 m. Distance between two adjacent pedestrians on either side of the road is a = 2.0 m and pedestrians on one side are displaced by a distance 0.5a with respect to pedestrians on the other side as shown in the figure, depicting the pedestrians by small circles. A boy distributing advertisement leaflets bypasses all the pedestrians. The boy and the pedestrians all are walking with the same constant speed v = 1.5 m/s. Starting from a pedestrian if the boy handovers leaflets to all the pedestrians he comes across, how much length Lof the road will he cover in 2.0 minutes?
