Apple trees are planted along a pathway at an equal distance of 3 m from each other.
- How far is the 1st tree from the 15th tree?
- How far is the 1st tree from the 30th tree?
- How far is the 7th tree from the 15th tree?
(a)
Distance between 1st tree and 15th tree
= (15 - 1) x 3
= 14 x 3
= 42 m
(b)
Distance between 1st tree and 30th tree
= (30 - 1) x 3
= 29 x 3
= 87 m
(c)
Distance between 7th tree from the 15th tree
= (15 - 7) x 3
= 8 x 3
= 24 m
Answer(s): (a) 42 m; (b) 87 m; (c) 24 m
