The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.What is the average speed of the runner for the entire race?
stopped time is 1.5 hours, so the time for last 195 mi is 6.5 - 2 - 1.5 = 3 hours.
Using the graph, we can see that the runner ran 0 m at the beginning of the race. The runner's average speed for the first 10 seconds is calculated as: Let's review.
The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.
Its average velocity might be 25 miles per hour due east.
Average speed can be viewed as the rate of change in distance with respect to time.
