To calculate the average speed of the school bus between 0 h and 2.340 h, we need to use the formula for average speed:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]
Step 1: Gather the relevant data
- Position (km) at 0.000 h: 0.0 km
- Position (km) at 0.024 h: 1.2 km
- Position (km) at 0.051 h: 2.8 km
- Position (km) at 0.084 h: 4.2 km
The time we want to consider is from 0 h to 2.340 h, but we do not have any position recorded at 2.340 h. Hence, we should determine the total distance traveled by the bus at the latest time provided, which is 0.084 h.
Step 2: Calculate the distance and time
- Total distance = Position at 0.084 h = 4.2 km
- Total time = 0.084 h
Step 3: Calculate the average speed
We can now plug these values into the average speed formula:
\[ \text{Average Speed} = \frac{4.2 \text{ km}}{0.084 \text{ h}} \approx 50 \text{ km/h} \]
Conclusion
The average speed of the school bus between 0 h and 2.340 h (based on available data) is approximately 50 km/h.
