Kevin drove for 4 hours and then stopped to eat dinner. The total distance he had driven at different time intervals is shown on the graph below.⬇️ • Using the information in the graph, determine Kevin’s average speed during these 4 hours.

• Kevin will drive for an additional 2 hours after dinner. He expects to drive 130 miles during these 2 hours, under the same driving conditions as the trip represented in the graph. Is this a reasonable expectation? Explain your answer and show your work.

If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.  

So firstly you have to calculate the speed of the first point, which is:  

20 miles/0.5 hour

That means: 40 miles/hour

That would be your first "speed"

Then you calculate all of them :speed1+speed2+speed3 = something.  

As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr

Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.

It is my first answer, and I hope I could help you a bit!
