Answer: Hello the chart related to your question is missing but I can provide a general answer based on the scope of your question
answer : Based on the assumptions and calculations below, John has drawn the best conclusion
Explanation:
Given condition : Temperature drops one ( 1 ) or two(2) degrees every Ten minutes
i.e. For every 1 hour the temperature will drop by either : 6°F or 12°F
Assuming : Current Temp = 80°F , Current Time = 5 pm
hence Temperature at 6 pm = ( 80 - 6 ) or ( 80 - 12 )
= 74°F or 68°F
From the above we can conclude that John has drawn the best conclusion
