Use an equation with the Unknown Multiplier to represent the total hours put in by the three people:
2x+3x+5x=110
x=11
Therefore, the person who worked the most hours put in 5(11) = 55 hours, and the person who worked the least hours put in 2(11) = 22 hours. This represents a difference of 55 − 22 = 33 hours.
