You can put this solution on YOUR website! What is Jeremiah's average speed during the interval he is traveling the fastest?
.
Where is the steepest line? That's what you're looking for. It would appear that this is the last interval, from hour 4 to hour 7. During that time, he traveled 190 miles. 190 miles divided by 3 hours = 63.33 miles per hour. The second interval looks similar. Let's calculate that. From hour 0.5 to hour 3, he traveled 140 miles (330 to 190). 140 miles divided by 2.5 hours = 56 miles per hour.
.
(The process is correct; the small lines are difficult for me to see, so doublecheck the actual numbers on your end.)
