Answer:
Average speed = Total distance ÷ Total time
Average speed = 16250 km ÷ 10 days = 1625 km/day
1 km = 1000 m
1625 km = 1625 × 1000 m = 1,625,000 m
1 day = 24 hours = 24 × 60 minutes = 1440 minutes
10 days = 10 × 1440 minutes = 14400 minutes
Average speed = 1,625,000 m ÷ 14400 minutes = 113.19 m/min
1 minute = 60 seconds
Average speed = 113.19 m/min ÷ 60 seconds/min = 1.8865 m/s.
