The relationship between the speed of travel and the distance traveled can be described by the equation d=rt where d = distance traveled in miles, r = speed (or rate) of travel in miles per hour, and t = time traveled in hours. Graph this function when the speed of travel, r, is 40 miles per hour.
To graph the function when the speed of travel, r, is 40 miles per hour, we need to plot points on a coordinate plane using the equation d=rt.
Let's choose a set of values for time traveled, t, and calculate the corresponding distance, d, using the equation. We can then plot these points and connect them to form the graph.
Let's choose three different values for time traveled, t: 1 hour, 2 hours, and 3 hours.
For t = 1 hour:
d = 40 * 1 = 40 miles
For t = 2 hours:
d = 40 * 2 = 80 miles
For t = 3 hours:
d = 40 * 3 = 120 miles
Now let's plot these points on a graph. We will use the distance traveled, d, on the y-axis and the time traveled, t, on the x-axis.
Point 1: (1, 40)
Point 2: (2, 80)
Point 3: (3, 120)
Once we have plotted these three points, we can connect them with a straight line to form the graph.
