A tree is 8 feet tall and grows 8 inches each year. In how many years will the tree reach a height of 30 feet?
Correct answer: B. 33
- A. 27
- B. 33
- C. 45
- D. 52
Explanation
The tree currently stands at 8 feet tall and needs to reach 30 feet, which means it must grow an additional 22 feet.The tree grows 8 inches per year. Since there are 12 inches in a foot, 8 inches equals 2/3 of a foot per year.To find the number of years required for the tree to grow those 22 feet, divide the total feet needed by the annual growth in feet:Number of years = 22 feet / (2/3 feet/year) = 33 years.Therefore, it will take 33 years for the tree to reach a height of 30 feet. Option B is correct. The other options result from errors in conversion or in calculating the growth period.
