Question

Mr chen planted 10 trees in a row. If the distance between any two consecutive trees is 15 metres. Find the distance from the first tree to the last tree.

Answer 1

The distance from the first tree to the last tree in Mr. Chen's row of 10 trees, with each pair of consecutive trees being 15 meters apart, is 135 meters.

Step-by-step explanation:

Mr. Chen planted 10 trees in a row with a distance of 15 meters between each pair of consecutive trees. To find the distance from the first tree to the last tree, we need to consider that there are 9 gaps between the 10 trees. Since each gap measures 15 meters, we will multiply 15 meters by 9 to calculate the total distance.

1. Identify that there are 9 gaps between 10 consecutive trees.
2. Multiply the number of gaps by the distance between two trees: 9 gaps × 15 meters/gap.
3. Calculate the total distance: 9 × 15 = 135 meters.

The distance from the first tree to the last tree is 135 meters.
