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?
Number of trees = 9
Distance b/w trees = 2.5 meters
Number of trees between 1st and 9th tree = 9 – 1 = 8
Total distance = distance between two trees * total number of trees
= 2.5 * 8 = 20 meters
Answer: Distance between 1st and 9th tree = 20 Meters
