Question

b. after the baby penguin hatches, it needs to grow up for about 150 days before it can start swimming. the ice shelf melts away in the summer when the surrounding temperature reaches about -4°c. what is the difference between the summer and winter outside temperatures?

Explanation:

Step1: Identify Winter Temperature (Assumption)

Assume winter temperature for penguins' habitat (e.g., Antarctica) is around \(-20^\circ\text{C}\) (common polar winter temp). Summer temp is \(-4^\circ\text{C}\).

Step2: Calculate Temperature Difference

Difference = Summer Temp - Winter Temp = \(-4 - (-20)\) = \(-4 + 20 = 16^\circ\text{C}\). (Note: If winter temp was different, adjust, but typical polar context uses \(-20^\circ\text{C}\) as winter baseline for penguins.)

Answer:

The temperature difference is \(16^\circ\text{C}\) (assuming winter temperature is \(-20^\circ\text{C}\); adjust if actual winter temp differs).
