Question

The graph represents the distance a car travels over time while on the highway. Which statement about the car's trip is accurate?

Answer 1

The car is a distance time graph which means that the gradient of the graph represents the speed. The steeper the gradient the faster the car. In this case, car B has the lowest gradient and is therefore, the least steep. This means that it has the slowest speed. Moreover, it also means that the rate of change of distance is lower.

Simply saying, the car with the least gradient will cover the least distance in the most time. The car with the steepest gradient will cover the most distance in the smallest time. These difference are plotted on the graph and are able to show the different scenarios at its best.
