Ben helped his parents plant a row of fruit trees.the row is 50 meters long.the distance between trees is 5 meters.how many trees did they plant?

50/5 + 1 = 11 (one is at x = 0)

This is for a 3 rd grade student

one at x = 0

then 10 more at 5, 10, 15, 20, 25 , 30, 35, 40, 45, 50

You always have one more fence post than panels of fencing

To find out how many trees they planted, we need to divide the total length of the row by the distance between the trees.

Given that the row is 50 meters long and the distance between trees is 5 meters, we can use the following formula:

Number of trees = Total length of the row / Distance between trees

Plugging in the values, we have:

Number of trees = 50 meters / 5 meters

Simplifying the equation, we get:

Number of trees = 10 trees

So, they planted 10 fruit trees.
