A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?
If you count the starting point: Chicago, 3 stops, New York, 1 stop, Chicago = ?
A plane that carries mail makes a round trip each day from Chicago to New York. It makes 2 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

i guess it would be 7 as the answer because: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........
It’s 5 you guys
To determine how many times the graph touches the horizontal axis, we need to consider the number of takeoffs and landings the plane makes in one day.
Given that the plane makes a round trip from Chicago to New York, we can break down the trip into two segments: Chicago to New York and New York to Chicago.
On the way from Chicago to New York, the plane makes 3 intermediate stops. Each stop corresponds to a landing, with the subsequent takeoff occurring shortly after. Therefore, there are a total of 3 landings and 3 takeoffs during this segment.
On the way back from New York to Chicago, the plane makes 1 intermediate stop. Similarly, this corresponds to a landing followed by a takeoff, resulting in 1 landing and 1 takeoff for this segment.
In total, the plane has 3 + 1 = 4 takeoffs and 3 + 1 = 4 landings in one day.
Since each landing and takeoff marks a point where the altitude of the plane touches the horizontal axis, the graph of the altitude will touch the horizontal axis 4 times during a day.
I have this problem too!
I can't figure it out either. lol
