Mango trees are planted along a pathway at an equal distance of 7 m from each other.
- How far is the 1st tree from the 13th tree?
- How far is the 1st tree from the 20th tree?
- How far is the 7th tree from the 13th tree?
(a)
Distance between 1st tree and 13th tree
= (13 - 1) x 7
= 12 x 7
= 84 m
(b)
Distance between 1st tree and 20th tree
= (20 - 1) x 7
= 19 x 7
= 133 m
(c)
Distance between 7th tree from the 13th tree
= (13 - 7) x 7
= 6 x 7
= 42 m
Answer(s): (a) 84 m; (b) 133 m; (c) 42 m
