Cooling rate

How does increasing the starting temperature of the water increase the cooling rate?
For one, there's this cool effect called the Mpemba effect stating that hot water freezes faster than warm water. But I expect that this is not the answer you're searching for.

Hot water has a faster cooling rate (the loss of heat energy) than cold water as it has a greater difference in temperature to the surroundings. This is Newton's law of cooling

Wikipedia definition of the law is " that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its environment"
