Question

There are 8 mango trees in a straight line. the distance between each mango tree with the other is 3 meters, find the distance between 1st and the last tree

Answer 1

Thank u... I hope my answer may satisfy u...

Answer 2

$Number \:of \:mango \:trees \:in \:a \\straight \: line (n) = 8$

$Distance \: between \:two \: consecutive \\trees (d) = 3 \:m$

$Distance \: between \: first \:tree \: and \\the \:last \:tree = (n-1) \times d \\= (8-1) \times 3 \\= 7 \times 3 \\= 21 \:m$

Therefore.,

$\red {Distance \: between \: first \:tree \: and }\\\red{the \:last \:tree } \green {= 21 \:m}$
