Answer:

124.88 km/h

34.69 m/s

Explanation:

1633.8 km = 1633800 m

13 hours 4 minutes 58 seconds = 13 + 4/60 + 58/3600 = 13.083 hours

13 hours 4 minutes 58 seconds = 13*3600 + 4*60 + 58 = 47098 seconds

So the average speed in km/h is

1633.8 / 13.083 = 124.88 km/h

The average speed in m/s is

1633800 / 47098 = 34.69 m/s
