Assume that Japan and Korea can switch between producing cars and producing airplanes at a constant rate. Japan Korea ro b. Hours Needed to Make 1 Car d. 3 Airplane 150 Quantity Produced in 2400 Hours Car Airplane 5 150 0 48 Refer to Table 3-10. We could use the information in the table to draw a production possibilities frontier for Japan and a second production possibilities frontier for Korea. If we were to do this, measuring cars along the horizontal axis, then the slope of Japan's production possibilities frontier would be -5 and the slope of Korea's production possibilities frontier would be -3. the slope of Japan's production possibilities frontier would be -0.2 and the slope of Korea's production possibilities frontier would be -0.33. the slope of Japan's production possibilities frontier would be 0.2 and the slope of Korea's production possibilities frontier would be 0.33. 80 16 16 the slope of Japan's production possibilities frontier would be 5 and the slope of Korea's production possibilities frontier would be 3.
