Answer 1

To calculate the average speed of the school bus between 0 h and 2.340 h, we can use the following formula:

\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]

1. Calculate the total distance: The bus starts at 0 km and ends at 16.3 km.

   \[ \text{Total Distance} = \text{Ending Position} - \text{Starting Position} = 16.3 \text{ km} - 0.0 \text{ km} = 16.3 \text{ km} \]

2. Calculate the total time: The starting time is 0 h and the ending time is 2.340 h.

   \[ \text{Total Time} = \text{Ending Time} - \text{Starting Time} = 2.340 \text{ h} - 0.000 \text{ h} = 2.340 \text{ h} \]

3. Calculate the average speed:

   \[ \text{Average Speed} = \frac{16.3 \text{ km}}{2.340 \text{ h}} \approx 6.96 \text{ km/h} \]

Thus, the average speed of the school bus between 0 h and 2.340 h is approximately 6.96 km/h.
