Pertanyaan
Jessica's plane and Kayle's plane take off at the same time. Lauren's plane leaves hour earlier than Maria's plane. Maria's plane leaves at least 2 hours after Kayla's plane. Each person's fight lasts 8 hours Marla's flight lands at 445 p.m. Which statement cannot be true? Kayla's flight takes off at 5:45 a.m. Lauren and Kayla take off at the same time. Lauren's flight starts at 7:45 a.m Lauren's plane takes off after Kayta's plane takes off. The latest that Jessica plane lands is 2:45 p.m.
Jawaban
* Marla's landing: 4:45 PM
* Marla's flight duration: 8 hours
* Marla's takeoff: 4:45 PM - 8 hours = 8:45 AM
* Maria's takeoff: Maria's plane leaves at least 2 hours after Kayla's plane.
Now let's examine each statement:
* Kayla's flight takes off at 5:45 AM: This is possible. If Kayla takes off at 5:45 AM, Maria could take off at 7:45 AM or later, satisfying the condition that Maria's takeoff is at least 2 hours after Kayla's.
* Lauren and Kayla take off at the same time: This is possible. If both take off at the same time, and Lauren's plane leaves an hour earlier than Maria's, this aligns with Maria's takeoff being at least two hours after Kayla's.
* Lauren's flight starts at 7:45 AM: This is possible. If Lauren takes off at 7:45 AM, and Maria takes off at 8:45 AM (at least 2 hours after Kayla's potential 5:45 AM takeoff), the condition is met.
* Lauren's plane takes off after Kayla's plane takes off: This is possible. As long as Maria's takeoff is at least two hours after Kayla's, Lauren's takeoff can be before or after Kayla's.
* The latest that Jessica's plane lands is 2:45 PM: Jessica's plane takes off at the same time as Kayla's. If Kayla takes off as early as 5:45 AM, and the flight is 8 hours, Jessica's plane would land at 1:45 PM. Therefore, the latest landing time for Jessica's plane cannot be 2:45 PM. This statement is impossible given the other constraints.
Therefore, the statement that cannot be true is: The latest that Jessica's plane lands is 2:45 PM.
