1. how far from the home did karen and her mother travel during the first hour of the trip?

2. calculate the average speed of the car during the first hour of the trip.

3. how far did karen and her mother travel during the second hour of the trip?

4. calculate the average speed of the car during the first two hours of the trip.

5. identify the time period(s) during the trip when the car was traveling at the greatest average speed.

6. identify the time period(s) during the trip when the car was stopped.

7. calculate the average speed of the car for the first three hours of the trip.

8. if karen and her mother take three hours to come home, calculate the average speed of the car for the trip home.

1).  The first green circle on the graph, at 1 hr, is up at 40 miles.

2).  (40 miles) / (1 hour)  =  40 mph

3).  The distance doesn't change during the second hour.
     They didn't travel at all during that hour.

4).  Average speed = (distance covered) / (time to cover the distance)
                             =      40 miles           /          2 hours
                             =                    20 mph during the first 2 hours

5).  The greatest average speed is the period where the graph
has the steepest slope.  That's during the first hour.

6).  The car was stopped during the whole 2nd hour and the whole 5th hour.

7).  At the end of 3 hours, the graph has moved up to 60 miles.
The average speed during those 3 hours is

                     (60 miles) / (3 hours)  =  20 mph .

8).  The farthest away from home they ever got was 76 miles.
If they take 3 hours to return, over the same route, then their
average speed on the return will be

           (76 miles) / (3 hours)  =  (25 and 1/3) miles per hour.

This is the answer of your question
