To find the rate at which the bus is traveling, we can determine the total distance traveled and the total time taken.
From the table, we know that:
- At 0 hours, the distance is 0 miles.
- At 2 hours, the distance is 120 miles.
- At 4 hours, the distance is 240 miles.
Let's use the data at the 4-hour mark to find the speed, as it gives us a good total distance covered.
Total distance covered: 240 miles
Total time taken: 4 hours
Now, we calculate the speed (rate) using the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Substituting the values we have:
\[ \text{Speed} = \frac{240 \text{ miles}}{4 \text{ hours}} = 60 \text{ mph} \]
Therefore, the rate at which the bus is traveling is 60 mph.
The correct response is:
60 mph
