To find the speed of the bus, we can use the distance and time data provided in the table.
We can calculate the speed using the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
From the table, let's use the data for the distance and time at 2 hours to find the speed, as this is one of the complete data points.
According to the table:
- Time spent driving = 2 hours
- Distance traveled = 120 miles
Now we can calculate the speed:
\[ \text{Speed} = \frac{120 \text{ miles}}{2 \text{ hours}} = 60 \text{ mph} \]
Therefore, the rate at which the bus is traveling is 60 mph.
