Pear trees are planted along a pathway at an equal distance of 3 m from each other.
- How far is the 1st tree from the 14th tree?
- How far is the 1st tree from the 20th tree?
- How far is the 7th tree from the 14th tree?
(a)
Distance between 1st tree and 14th tree
= (14 - 1) x 3
= 13 x 3
= 39 m
(b)
Distance between 1st tree and 20th tree
= (20 - 1) x 3
= 19 x 3
= 57 m
(c)
Distance between 7th tree from the 14th tree
= (14 - 7) x 3
= 7 x 3
= 21 m
Answer(s): (a) 39 m; (b) 57 m; (c) 21 m
