Apilot was scheduled to depart at 4: 00 pm, but due to air traffic, her departure has been delayed by 15 minutes. air traffic control approved a new flight plan that will allow her to arrive two times faster than she calculated in her original flight plan. let x represent the time, in minutes, of her original flight. create an equation that can be used to predict the number of minutes after 4: 00 pm she will arrive at her destination. y = 2x + 15 y equals one half times x plus 15 y equals one half times x minus 15 y = 2x − 15

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
