Question

Trees were planted along a road 45km long. If the trees were planted 15m apart on both sides. How many trees were planted altogether

Answer 1

Step-by-step explanation:

To understand this, let's focus on one side to begin with.

If the straight road was 20 meters, you could have planted two trees.

If it was 40 meters, you could have planted three trees

If it was 'n' meters, you could have planted n/20 + 1 trees

Number of trees that can be planted on one side = 1760/20 + 1 = 88 + 1 = 89

Total trees = 89*2 = 178
