Question 1120889
trees are planted at intervals of 10 meters along one side of a straight path.


the first tree is planted at the start and the last tree is planed at the end.


the length of the path is 230 meters.


230 / 10 = 23 trees.


to see if this formula is good, try a smaller distance that you can easily see if it's correct.


suppose the distance was 20 meters.


20 / 10 = 2.


1 at the start then 1 at 10 meters then 1 at 20 equals 3.


suppose the distance was 30 meters.


30 / 10 = 3.


1 at the start then 1 at 10 then 1 at 20 then 1 at 30 = 4.


the answer appears to be 1 more than the total distance divided by the interval.


that makes your answer 230 / 10 = 23 + 1 = 24 trees required.
