Salle plants 4 saplings in a row in her garden. The distance between two adjacent saplings is 3/4 m. Find the distance between the first and the last saplings.

The distance of the 2nd sapling from the 1st is 3/4 m; the 3rd sapling from the 2nd is 3/4 m and the last sapling (4th) from the 3rd is 3/4 m.

Answer: The distance between the first and the last sapling is 9/4 m.

Let's find the distance between the first and the last saplings.

Explanation:

The following diagram shows the arrangement of saplings.

Distance between two adjacent saplings = 3/4 m (given)

Hence, the distance between the first and the last sapling = (3/4) m × 3 = 9/4 m (As there are three divisions in the diagram above)

Thus, the distance between the first and the last sapling is 9/4 m.
