The chart below shows the change in the temperature. John says the temperature at 6:00 p. M. Will be about 75º F because the temperature has been dropping one or two degrees every ten minutes. Fred says the temperature at 6:00 p. M. Will be about 72º F because the temperature has been dropping one or two degrees every ten minutes. Who has drawn the best conclusion, John or Fred?

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

answer; i believe the correct answer is ( quakers);
