Lamp posts are positioned at intervals of 120 m along a road and pots of bougainvillea plants placed at intervals of 96 m. The first pot of bougainvillea plant is placed at the foot of the first lamp post.
a) If the last pot of bougainvillea plant is placed at the foot of a lamp post, find the distance between the first and the last pot of plant.
b) Find the total number of lamp posts and pots of bougainvillea plants within this road segment.
** Need help with b). Thank you in advance.
