1. The problem involves understanding the distance measurement given as 85 hectometers. 2. A hectometer (hm) is a unit of length in the metric system equal to 100 meters. 3. To find the distance in meters, multiply 85 by 100: $$85 \times 100 = 8500$$ meters. 4. This means the grandmother's house is approximately 8500 meters from the current location. 5. For further intuition, convert meters to kilometers since 1000 meters = 1 kilometer: $$\frac{8500}{1000} = 8.5$$ kilometers. 6. Therefore, the grandmother's house is about 8.5 kilometers from here, which is a clearer and commonly used distance measurement.
