Question

Your graphing the speed your car goes on the interstate from the time you enter the ramp until you arrive at the next exit ramp 6 miles away. The speed of the highway is 70 mph. The X axis represents time and Y represents speed. The graph has five tick marks on the X axis and 10 tick marks on the Y axis. What would be a good scale for each axis?

Answer 1

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Step-by-step explanation:

The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.
