Questions & Step-by-Step Solutions
A researcher finds that a certain plant species grows at a rate of 5 cm per month. How tall will the plant be after 2 years?
Step 1: Determine how many months are in 2 years. There are 12 months in a year, so 2 years is 12 months/year * 2 years = 24 months.
Step 2: Find out how much the plant grows in one month. The plant grows 5 cm each month.
Step 3: Calculate the total growth over 24 months. Multiply the monthly growth (5 cm) by the total number of months (24 months): 5 cm/month * 24 months = 120 cm.
Step 4: The total height of the plant after 2 years is 120 cm.
