There are nine mango trees in a straight line. The distance between each mango tree is 2.5 metres. What is the distance between the first tree and the ninth tree?
Answer: (1) 20 m
The number of mango trees in a line = 9
The distance between each mango tree = 2.5 m
The distance between first tree and the ninth tree = 8 x 2.5 = 20 m.
Hence, the answer is (1) 20 m.
