A chemist recorded the change in temperature of a cooling liquid as −25.5°F over a 1.5 minute period. The temperature fell at a constant rate. What was the rate of change in temperature? Enter your answer in the box.

Respuesta :

The rate of the change of the temperature is calculated by dividing the change in temperature in °F by the total duration or time in minute. That is,
                   rate of change in temperature = -25.5°F / 1.5 min
                                                                         = -17°F / min
Thus, The temperature changes by -17°F per minute. 

yep it is -17 per min i just did the test
