20 is the only difference (simple)

Answer 2

Answer:

60°C is the difference

Step-by-step explanation:

just extend the two temperatures with intervals

• +40°C ---- (0)
• +30°C ---- (1)
• +20°C ----(2)
• +10°C ----(3)
• 0°C ----(4)
• -10°C -----(5)
• -20°C -----(6)

difference between each interval is about 10°C

Now count is 6

multiply the count and difference

10°C X 6 = 60°C
