Plzz help Logarithmic functions? Suppose the temperature in Denver, Colorado was 55°F when a 5°F arctic cold front moved over the state. Using k = 0.012, how long would it take a puddle of water to freeze? (Recall that water freezes at 32°F.) A. just over 51 minutes B. just over 55 minutes C. just over 61 minutes D. just over 65 minutes Plzz help Logarithmic functions?

(Recall that water freezes at 32°F.)

T = R + (T ) – R)e-kt T = temperature of the object after t minutes T ) = initial temperature R = temperature of the surroundings k = cooling rate (depends on the object and conditions)
