In a Nutshell Planting Trees Along a Road

We are trying to plant trees at regular intervals along one side of a
road. The length of the road is 12 m. Draw dots on the locations where
trees will be planted, and fill in the . Trees must be planted at the
start and end points.

1m
Trees are planted 2 m apart

Number of Trees: 7
Number of Intervals Between Two Adjacent Trees: 6

Trees are planted 3 m apart
Number of Trees:

Number of Intervals Between Two Adjacent Trees:
Trees are planted 4 m apart
Number of Trees:

Number of Intervals Between Two Adjacent Trees:

How are the number of trees and the number of intervals between two
adjacent trees related?

Planting Trees
When trees are planted at regular intervals in areas where the
start and end points meet:
(Number of Trees) (Number of Intervals)
When trees are planted along one side of a road at regular
intervals, with trees planted at the start and end points:
(Number of Trees) (Number of Intervals) 1
