There are 8 mango trees in a straight line. The distance between each mango tree is 3 meters. What is the distance between the first mango tree and the eight mango tree?

A) 24

B) 27

C) 30

D) 21

Step-by-step explanation:

The distance between each tree =3

7th and 6th =3and so on

8th to 7th + 7th to 6th + 6th to 5th + 5th to 4th + 4th to 3th + 3th to 2nd + 2nd to 1st

7 (3) =21
