Oak trees line both sides of a street for a length of 4/10 of a kilometer. If there is 15 meters of space between the trees, and each tree is 1 meter wide, how many trees are there along the street?
Answer/Solution
a) 26
Steps/Work
There is a gap of 15 m between every 2 trees , each tree is 1 m wide.
4/10 of 1 km = 400 m
Lets assume that x trees are planted So equation is
x*1 +(x-1)*15 = 400
Solve for x and we get x = 26, answer is A
4/10 of 1 km = 400 m
