Solution Steps

Step 1: Identify the slope of the blue curve

The slope of the blue curve measures the plane's rate of ascent.

Step 2: Determine the unit of measurement for the slope

The unit of measurement for the slope of the curve is feet per minute.

Step 3: Calculate the slope at point A

At point A, the slope of the curve is 10,000 feet / 2 minutes = 5,000 feet per minute, which means that the plane is ascending at a rate of 5,000 feet per minute.

Final Answer

  1. The slope of the blue curve measures the plane's rate of ascent.
  2. The unit of measurement for the slope of the curve is feet per minute.
  3. At point A, the slope of the curve is 5,000 feet per minute, which means that the plane is ascending at a rate of 5,000 feet per minute.
