Questions & Step-by-Step Solutions
If a tree absorbs 22 kg of CO2 per year, how much CO2 will 10 trees absorb in 5 years?
Step 1: Determine how much CO2 one tree absorbs in one year, which is 22 kg.
Step 2: Calculate how much CO2 10 trees will absorb in one year by multiplying 22 kg by 10 trees. This equals 220 kg.
Step 3: Now, calculate how much CO2 those 10 trees will absorb in 5 years. Multiply the yearly absorption (220 kg) by 5 years. This equals 1100 kg.
Multiplication and Unit Conversion – The question tests the ability to multiply quantities over time and understand the relationship between units (kg, trees, years).
