In order to calculate average speed we will calculate the total distance in meters traveled by cindy.

Distance = 2 Km

1 km = 1000m

So distance in meters = 2000 m

Then let us calculate the total time taken by cindy to cover these 2000 meters

Total time in minutes = 2 + 4 + 1 + 3 = 10 minute

Average speed = total distance  / total time

Average speed = 2000 m / 10 minutes

average speed = 200 m / min
