Why does ice melt faster in water than alone in air?
Does it take longer for a plane to fly east than to fly west?

Anyone want to answer them?

ice melts in water more quickly cause of the interactions between water molecules, as compared to particles in the air. Since considering that there is a hydration layer over the ice, its easier for heat transfer into ice, thus providing it enough energy to change states...in air, there isn't as much a layer of "particles", and its not as dense too...

airplane flying east/west...can't remember the answer, but it shouldn't be too difficult to work out....let's just say if you fly from NY, east and west towards SG...it probably the same, unless some time difference thing screws it up...
