elapsed time = 30 minutes is 0.5 hr
distance traveled = 20 km
speed = distance traveled / elapsed time
speed = 20 km / 0.5 hr
speed = 20 / 0.5 km/hr
speed = 40 km/hr
elapsed time = 30 minutes = 1800 seconds
distance traveled = 20 km = 20,000 m
speed = distance traveled / elapsed time
speed = 20,000 m / 1800 s
speed = 200 m / 18 s = 11.11 m/s.
