Two cars drive on the same highway in the same direction. The graphs show the distance, d, of each one as a function of time, t.
andrey2020 [161]

Answer:

  • Car B

Step-by-step explanation:

<u>The equation for the speed is:</u>

  • s = d/t

From the equation we see for the same t the speed is greater if d is greater.

We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.

It obvious the graph of the Car B will have a greater d- value.

It means that Car B has a greater speed so it is faster that Car A.
