To determine the average speed of the bus between 2.8 km and 4.2 km, we need to know the time taken by the bus to travel between these two distances.
Average speed is calculated using the formula:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]
First, calculate the distance traveled:
\[ \text{Distance} = 4.2 , \text{km} - 2.8 , \text{km} = 1.4 , \text{km} \]
Next, we would need the total time taken to travel those 1.4 km. Unfortunately, without the time data from the pickups table, I cannot accurately calculate the average speed.
Can you provide the time taken for the bus to travel from 2.8 km to 4.2 km?
