farmer nick planted a line of coconut trees along the length of his land. If he planted them 4m apart and the distance between the 1st and last tree last trees is 100m. Calculate the number of trees he planted.

24

25 trees

4m×25=100m
100m÷4m=25

To calculate the number of trees Farmer Nick planted, we need to find the total number of gaps between the trees that are 4 meters apart.

The distance between the first and last tree is 100 meters, and each gap between trees is 4 meters. This means that the number of gaps between trees is given by dividing the total distance by the gap size:

Number of gaps = Total distance / Gap size
Number of gaps = 100 m / 4 m
Number of gaps = 25

However, the number of gaps will be equal to one less than the total number of trees planted. For example, if there are two trees, there is one gap between them. So to find the number of trees, we need to add 1 to the number of gaps:

Number of trees = Number of gaps + 1
Number of trees = 25 + 1
Number of trees = 26

Therefore, Farmer Nick planted a total of 26 coconut trees.
