Q.5 Distance between two adjacent saplings is 23 m. There are seven
saplings in a row. Find the distance between
the first and the last
sapling?



Answer :

To determine the distance between the first and the last sapling when there are seven saplings in a row with a distance of 23 meters between each adjacent pair, follow these steps:

1. Understand the spacing: When there are 7 saplings lined up, there are gaps or intervals between them. The number of these gaps is always one less than the number of saplings.

2. Calculate the number of intervals: With 7 saplings, there are [tex]\(7 - 1 = 6\)[/tex] intervals between them.

3. Determine the distance of each interval: Each of these intervals is 23 meters.

4. Calculate the total distance: Multiply the number of intervals by the distance of each interval to get the total distance between the first and the last sapling.
[tex]\[ \text{Total distance} = \text{Number of intervals} \times \text{Distance between each interval} \][/tex]
[tex]\[ \text{Total distance} = 6 \times 23 \, \text{meters} \][/tex]
[tex]\[ \text{Total distance} = 138 \, \text{meters} \][/tex]

Therefore, the distance between the first and the last sapling is 138 meters.
