When I look closely at the question, I see that it describes the biker's speed as "20 hours per kilometer".
If I accept that description literally, then it takes him 100 hours = [ 4days 4hours ] to cover 5 km.
If "h/km" was a typo, and his speed is really "20 km/h", then it takes him (20/5) = 4 hours.
Ok, SO if the cyclist travels 12 km/h and he travels for 5 hours, 12 x 5 is 60 so 60 kilometers.
40 km per hour. 20 x 2 because that is in a half hour.
4km
16 meters per second
The average speed is (60 km) / (2 hr) = 30 km/hr. The speed along the way would most likely vary above and below that number.
40km per hour
16 km is not a speed (average or otherwise), it is a distance. It is therefore impossible to answer this question.

a cyclist
Cycler's speed = 400/20 = 20 meters per second. Skier's speed = 1500/60 = 25 meters per second. The skier's average speed during his minute is 25% faster than the cyclist's average speed during his 20 seconds.
