Can any one solve this to me


A cup of coffee is taken from a coffeemarker at 96C and left on the office table. In the air-conditioned office, the temperature is held at 19C. After 5 minutes, the coffee's temperature is 37C.
1-How much longer will it take the coffee to loose its taste quality, to cool down to the temperture of 22C?
2-Assume the coffee is left on the table of an outside cafe on a hot summer day when the temperature is 34C and on a cold winter day when the temperature is 6C. Get the expression for the coffee temperature as a function of time for these cases in form.
3-Plot the graphs T versus t for the all three environments using the same coordinate axes.
4-From the graphs, make an estimate when the coffee should be drunk in each situation(in office,winter,summer)if the coffee is supposed to be best at temperature 60C.

MATH IS MY WORST SUBJECT.
but that's not the point, right?
the point is that i want to help any way i can.

96C- 37C = 59C was lost within 5 minutes.

37C- 22C = 15C, is what will take to get to 22C.

to lose 15C will take less than 5 minutes, we know that.
300 seconds in 5 minutes.
took about 5 seconds for each degree to cool.

34C on a hot day, which is 15C more than the regular day.
6C which is 13C less than on the regular day.


OMG.
i just lost it.
and im sure i lost you too.

SORRY. im a loser, i dont know anything.
i bet all those are wrong.

SORRY. just wanted to take a stab at it.

im sure you have a math book. look over the examples.
sorry.

GOOD LUCK.
GOOD LUCK.
