The graph represents the distance in miles, y, that Car A travels in x minutes. The function y = 5 6 x represents the distance, y, that Car B travels in x minutes. Both cars are moving at a constant rate of speed. Which BEST compares the rates of the two cars?

Hello! Remember that you need to write complete questions in order to get good and exact answers. Here you haven't provided any graph so I could help you giving you my own graph. The relationship between speed, time and distance is as follows:

So represents slope of a line that passes through the origin. In this case:

So:

The graph below (Car A) comes from the following equation:

And the equation for car B is:

By comparing them, car A moves faster than car B because:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
