Constance drove 17 kilometers 25 meters from her college to her house for the weekend. Her father drove her back to her college the following day, Monday. Her father drove a distance of 26,400 meters. Who drove a longer distance?
Understand the Problem
The question asks us to determine who drove a longer distance between Constance and her father. Constance drove 17 kilometers and 25 meters from her college to her house, and we also know the distance her father drove. To solve this, we need to convert both distances to the same unit (meters) and then compare them.
Answer
Constance's father drove a longer distance.
Answer for screen readers
Constance's father drove a longer distance.
Steps to Solve
- Convert Constance's distance to meters
Since 1 kilometer is equal to 1000 meters, 17 kilometers is equal to $17 \times 1000 = 17000$ meters. So, Constance drove $17000 + 25 = 17025$ meters.
- Compare the distances
Constance drove 17025 meters and her father drove 26400 meters. Since $26400 > 17025$, her father drove a longer distance.
Constance's father drove a longer distance.
More Information
The father drove 9375 meters farther than Constance. $26400 - 17025 = 9375$
Tips
A common mistake is not converting kilometers to meters before comparing the distances or making a mistake during conversion.
