A coffee's temperature changed by -54°F in =

$= 22\frac{1}{2} \: minutes$

The temperature change in the coffee each minute :-

$= - 54 \div 22\frac{1}{2}$

$= - 54 \div \frac{(2 \times 22 + 1)}{2}$

$= - 54 \div \frac{45}{2}$

$= - 54 \times \frac{2}{45}$

$= \frac{ (- 54 \times 2)}{ \: \: 45}$

$= \frac{ - 108}{ \: \: \: 45}$

$\color{magenta} = - 2.4°F$

Therefore , the temperature change in the coffee each minute was = -2.4°F .
