Temperature 5

Temperature outside starts at 0 Fahrenheit. Over time the temperature changes at a rate of -0.6 Fahrenheit per hour. How long will it take for the temperature to reach -4.5 Fahrenheit?

Correct answer:

t =  7.5 h

Step-by-step explanation:

t1=4.5 °F t0=0 °F r=0.6 °F/h  t=(t1t0)/r=((4.5)0)/(0.6)=7.5 h
