Understanding Average Speed
Average speed is defined as the total distance traveled divided by the total time taken. In this case, the car travels two segments of 30 km each at different speeds.
Distance and Speed Segments
- First Segment:
- Distance: 30 km
- Speed: 40 km/h
- Second Segment:
- Distance: 30 km
- Speed: 20 km/h
Calculating Time for Each Segment
- Time for First Segment:
- Time = Distance / Speed = 30 km / 40 km/h = 0.75 hours
- Time for Second Segment:
- Time = Distance / Speed = 30 km / 20 km/h = 1.5 hours
Total Distance and Total Time
- Total Distance:
- 30 km + 30 km = 60 km
- Total Time:
- 0.75 hours + 1.5 hours = 2.25 hours
Calculating Average Speed
- Average Speed Formula:
- Average Speed = Total Distance / Total Time
- Average Speed = 60 km / 2.25 hours ≈ 26.67 km/h
Conclusion
The car's average speed over the entire journey is approximately 26.67 km/h. This calculation highlights how varying speeds affect overall travel time and average speed, illustrating the importance of understanding speed in travel planning.
