Final answer:
The unit rate of the tree's growth is calculated by dividing its height, 58 meters, by the number of years it has been growing, which is 125, resulting in a growth rate of 0.464 meters per year.
Step-by-step explanation:
The student is asking to calculate the unit rate at which a tree grows in Leila's backyard. The tree is 58 meters tall and it has been growing for 125 years. The unit rate is found by dividing the total height of the tree by the number of years it has been growing.
To calculate the unit rate in meters per year, you would perform the following calculation:
Unit rate = Total height / Number of years
Unit rate = 58 meters / 125 years
After performing the division, the unit rate would be 0.464 meters per year.
