Final answer:
When two planes leave O'Hare Airport simultaneously, the scenarios can include flying in the same direction, opposite directions, departing for different cities, or departing at different times.
Step-by-step explanation:
When two planes leave O'Hare Airport simultaneously, we can consider the different scenarios:
- If the two planes are flying in the same direction, they have the same departure time and will arrive at their destinations at different times. This scenario does not involve arrivals or departures at O'Hare Airport.
- If the two planes are flying in opposite directions, they will arrive at their destinations at the same time. This scenario involves two arrivals and two departures at O'Hare Airport.
- If the two planes are departing for different cities, they will have different departure times and will arrive at their destinations at different times. This scenario involves two departures at O'Hare Airport.
- If the two planes are departing at different times, they may or may not arrive at their destinations at the same time. This scenario involves either one arrival and one departure or two departures at O'Hare Airport, depending on the specific departure times.
