1. The graph presents the travel data for four different cars showing the distance they are from home (in miles) over time (in hours). Which car has the highest rate of speed?
Answer: A
Car A has the highest rate of speed.
Car A exhibits the greatest distance covered over time compared to the other cars, indicating it has the highest rate of speed.
A) A
Option A is correct because it represents the car that travels the farthest distance within the same time frame as the others, thus demonstrating the highest speed. The graph clearly shows that Car A's line has the steepest slope.
B) B
Option B is incorrect as it shows a lesser distance traveled than Car A over the same period. The slope of Car B's line is not as steep, indicating a slower speed compared to Car A.
C) C
Option C is also incorrect because it represents a car that covers even less distance than Car B. The slope of Car C's line is the least steep, confirming that it has a lower speed than both Car A and Car B.
D) D
Option D is incorrect as well since it indicates a distance traveled that is less than all the other cars. The line for Car D is the flattest, signifying the slowest rate of speed among the four options.
Conclusion
Car A is definitively the correct answer because it demonstrates the highest speed through the greatest distance covered over a given time. All other options fail to match this performance, with each showing a slower rate of speed based on their respective distances and slopes on the graph.
