To calculate the speeds of the red and blue cars, we need to know the distances they traveled and the time it took for each.
Red Car
Assuming we have the distance traveled by the red car from the graph (let's say it traveled a certain distance by a specific time, which you'll need to provide if not already known). For instance, if the red car traveled 240 miles in 4 hours, we would calculate its speed as follows:
\[ \text{Speed of Red Car} = \frac{\text{Distance}}{\text{Time}} \]
\[ \text{Speed of Red Car} = \frac{240 \text{ miles}}{4 \text{ hours}} = 60 \text{ miles per hour} \]
Blue Car
For the blue car, we can use the table provided. The table shows miles traveled per hour.
From the data provided:
- For 6 hours: 324 miles
- For 7 hours: 378 miles
- For 8 hours: 432 miles
Now, let's calculate the speed for each timeframe.
Speed for 6 hours:
\[ \text{Speed} = \frac{324 \text{ miles}}{6 \text{ hours}} = 54 \text{ miles per hour} \]
Speed for 7 hours:
\[ \text{Speed} = \frac{378 \text{ miles}}{7 \text{ hours}} = 54 \text{ miles per hour} \]
Speed for 8 hours:
\[ \text{Speed} = \frac{432 \text{ miles}}{8 \text{ hours}} = 54 \text{ miles per hour} \]
Conclusion
Now, if we go with an example for the red car's speed:
- Speed of Red Car: 60 miles per hour (example value)
- Speed of Blue Car: 54 miles per hour
Based on these potential values:
The red car is faster.
You will need to replace the red car's speed with the actual value derived from the graph you have. If you provide that information, I can give you exact comparisons!
