You place a cup of 220 degrees f hot chocolate on a table in a room that is 72 degrees f, and 12 minutes later, it is 205 degrees f. approximately how long will it be before the coffee is 175 degrees f? round to the nearest minute. (use newtons law of cooling: t(t)=ta+(t0-ta)e^-kt

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
