Question: If a tree absorbs 50 kg of CO2 per year, how much CO2 will 5 such trees absorb in 4 years?

Options:

Correct Answer: 800 kg

Solution:

5 trees * 50 kg/tree/year * 4 years = 1000 kg

If a tree absorbs 50 kg of CO2 per year, how much CO2 will 5 such trees absorb in 4 years?

If a tree absorbs 50 kg of CO2 per year, how much CO2 will 5 such trees absorb in 4 years?

Step 1: Identify how much CO2 one tree absorbs in a year, which is 50 kg.
Step 2: Calculate how much CO2 5 trees absorb in one year by multiplying the amount one tree absorbs by the number of trees: 50 kg/tree/year * 5 trees.
Step 3: Calculate the total CO2 absorbed by 5 trees in one year: 50 kg * 5 = 250 kg.
Step 4: Now, calculate how much CO2 these 5 trees will absorb in 4 years by multiplying the yearly absorption by 4: 250 kg/year * 4 years.
Step 5: Perform the final calculation: 250 kg * 4 = 1000 kg.

Multiplication and Unit Conversion – The question tests the ability to multiply quantities and understand the units involved in the context of CO2 absorption over time.
