Want this question answered?
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.
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
Travelling faster than the speed of sound causes a loud noise called the sonic boom.
Light travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
Faster in water than in air.

Probably not. Nothing travels faster than the speed of light.
Sound travels faster through dense objects.
The speed of light (ca. 300,000 km/second) seems to be the speed limit in the Universe. Nothing is known to travel faster than light; it seems likely that travelling faster than light is not possible.
light travels faster in vacuum.
A Worm travels faster than a Snail.
lightning travels faster. Light is faster than sound.

A lightning storm is an excellent example of light travelling faster then sound because of the fact that unless it is directly above you the lightning always streaks first and then you hear the thunder.
i.e. mechanical waves travelling through water? Light of course. Otherwise how would you see the ripples? Light travels at 299,792.458 km/s.
The duck that goes 60m in 5 seconds. But, why would you ask such a ridiculous question? The duck that goes 60m in 5 seconds. But, why would you ask such a ridiculous question?
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
