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 result:

t =  7.5 h

Solution:

t1=4.5t0=0r=0.6F/h  t=(t1t0)/r=((4.5)0)/(0.6)=152=152 h=7.5 h
