Correct Answer:
C. 200 km
The correct answer is 200 km. Distance is calculated using the formula: Distance = Speed × Time.
Step-by-Step Calculation
- Given: Speed = 80 km/h, Time = 2.5 hours.
- Apply Formula:
Distance = 80 × 2.5
Distance = 80 × (2 + 0.5) = 160 + 40 = 200 km - Why Other Options Are Wrong:
- 160 km: This would be the distance for 2 hours (80 × 2), forgetting the additional 0.5 hour.
- 180 km: No valid calculation yields this result.
- 240 km: This would be for 3 hours (80 × 3), an overestimate.
- Units Check: km/h × hours = km. The units are consistent.
Therefore, the vehicle covers 200 km.
