Distance of the trip=2400km-2000km=400km
Time taken for trip=8hours
Average speed=Total distance÷ total time taken=400km÷8 hours=50km/h
50km=50000m
1 hour=3600sec
50km/h=50000m÷3600sec=13•8m/s
Time taken for trip=8hours
Average speed=Total distance÷ total time taken=400km÷8 hours=50km/h
50km=50000m
1 hour=3600sec
50km/h=50000m÷3600sec=13•8m/s
