In a demonstration of our memories of pain, researchers asked subjects to put one hand in painfully cold water for 60 seconds and then the other hand in the same painfully cold water for 60 seconds, followed by a slightly less painful 30 seconds more. Which experience would you expect the subjects to recall as MOST painful?

The first 60 Seconds by the first hand put in the painfully cold water and the last 30Seconds will be most painful.

Explanation:

The peak–end rule is a psychological heuristic that tries to say that people judge an experience largely based on how they felt at its most intense point and at its end, instead of based on the net Total or average of every moment of the experience. This effect occurs regardless of whether the experience is good or bad, pleasant or unpleasant. This doesn't mean that other information from the peak and end of the experience is lost, it is simply not used to judge how painful or sweet that experience is. The peak-end rule explains why the first 60 seconds and the last 30 seconds will be most felt by the Subjects used in the research according from the question.

transportation i would say maybe sorry it its not correct
