Answer: 1080 km.
Explanation: Since she bikes 30 weekends per year, and for each of those 30 weekends she rides 9km, we can simply multiply 30*9 and find that she bikes 270km a year. However, the question asks how much she bikes in four years. To solve for this we can multiply our yearly distance by four, resulting in 1080 km.
