Cannon Lane · Answer 1

Average speed = (total distance covered) / (time to cover the distance)

Total distance = (250m + 1,000m + 350m + the rest) = 2,000 meters

Total time = (2min + 4min + 1min + 3min) = 10 minutes

Average speed = (2,000 meters) / (10 minutes)

Average speed = 200 meters per minute

Laney Smith · Answer 2

Total distance = 2000m

Total time = 10min

Average speed = 2000/10 = 200m/min
