Question 1120889: Trees are planted at intervals of 10 m along one side of a straight path. The first tree is planted at the start and the last tree is planted at the end of the path. Given that the length of the path is 230m, calculate the total number of trees planted

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.
