Luden [163]
<h3>Solution :</h3>

Distance between first tree and last tree is 140m .

And distance between each tree (d) = 5 m

let's solve for number of trees (n) :

\hookrightarrow \: (n - 1)d = 140

\hookrightarrow \: (n - 1)5 = 140

\hookrightarrow \: n - 1 =  \dfrac{140}{5}

\hookrightarrow \: n = 28 + 1

\hookrightarrow \: n = 29

hence, total number of trees = 29.
