Question

Find the maximum number of trees which can be planted 20m apart on two sides of a straight road 1760m long

Answer 1

Hey,sup!

As per the question,

On one side number of trees that can be planted= 1760/20 + 1 = 88+1 = 89.

So on both sides number of trees that can be planted= 89×2 = 178 trees.

Hope it helps.

Answer 2

178 trees can be planted 20m apart on two sides of a straight road of 1760m long

Given:

Trees are to be planted 20m apart on two sides of a straight road 1760m long.

To find:

The maximum number of trees which can be planted.

Solution:

Step 1 of 2:

Let,

The number of trees planted on one side of the road = ( Length of the road / Distance between the trees ) + 1

Length of the road = 1760m

Distance between the trees = 20m

The number of trees planted on one side of the road = $\frac{1760}{20} +1$

The number of trees planted on one side of the road = 88 + 1

The number of trees planted on one side of the road = 89 trees

Step 2 of 2:

The number of trees planted on one side of the road = 89 trees

The number of trees planted on two side of the road = 2 × 89

The number of trees planted on two side of the road = 178 trees

The maximum number of trees which can be planted is 178 trees
