1670 km/h; 40 200 km/day
a) Velocity in kilometers per hour
The conversion factors are 1 km/1000 m, 60 s/1 min, and 60 min/1 h.
We can string these together to get
Velocity = (465 m/1 s) x (1 km/1000 m) x (60s/1min) x (60 min/1 h)
= 1674 km/h
= 1670 km/h (three significant figures)
b) Velocity in kilometers per day
The conversion factor is 24 h/1 day.
Velocity = (1674 km/1 h) x (24 h/1 day) = 40 200 km/day
