Final answer:
To calculate how far apart the temperatures in the Gobi Desert are from the winter low to the summer high, you subtract the lower temperature from the higher temperature, considering the negative value. The result is that the two temperatures are 130 degrees Fahrenheit apart.
Step-by-step explanation:
To find out how far apart the temperatures in the Gobi Desert are between the winter low of -40°F and the summer high of 90°F, you simply calculate the difference between the two temperatures. To do this, you take the higher temperature and subtract the lower temperature, keeping in mind that the lower temperature is a negative number:
90°F - (-40°F) = 90°F + 40°F = 130°F.
So, the temperatures in the Gobi Desert are 130 degrees Fahrenheit apart.
