I am having a hard time solving this problem. The formula given is:

T=Tin - (Tin - Tinit.)e(-v/v)t

If the initial temperature Tinit is 115 (degrees F), the cold water temperature is 35 (degrees F) (1.7 degrees C), and the volume and volumetric flow rate are 3,000 liters and 30 liters per minute, respectively,

(a) Calculate the expected water temperature at 5-minute intervals for the first 60 seconds after the flow of cold water is established;
