Ice cubes melt faster in hot water. Hot water has more heat energy to overcome the forces of attraction between water molecules in ice. Go look up the kinetic particle theory.
Water :)
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
because water heats up faster

Ice cubes will melt faster in darker colour water than lighter colour water
When sugar is in water, it dissolves faster than salt does. I do not know the scientific reason why, but sugar melts faster.
Hot water
yes
depends!
Water has a higher temperature in ice causing it to melt faster.
If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.
If the initial temperature of the lemonade is equal for both the water and the ice then the cubes would cool lemonade faster because they have a lower initial temperature.
