Hello everyone. This is a rather easy question, so here are the results. It starts at 90 degrees and must stay above 60. Starting at the top (answer, to see if it is right), 10 minutes, times 3 degrees per minute. U get 30 degrees. 90-30= 60, and it has to be ABOVE 60, so it must be in the cooler for FEWER THAN 10 MINUTES. and the answer is A to all the confused people out there. My explanation may have been confusing lol. Thank you, and God Bless!
