Boiling temperature is 212 F
Let +t+ = number of minutes to boil
++85+%2B+15.5t+=+212+
+15.5t+=+127+
+t+=+8.194+
+.194%2A60+=+11.6+
8 minutes 11.6 sec

Assume boiling point of soup = 100 deg
Room temperature 85 deg
temperature to raise 15 deg
15.5 deg in 1 minute
15 deg rise in 15/15.5
0.97 hours = 58 minutes

In his post, @mananth made a fatal error.

He missed to convert boiling point 100 deg Celsius to degrees Fahrenheit, 212 F,
and got absurdist answer.

So, we should calculate the time as

        t = %28212-85%29%2F15.5 = 8.194 minutes, or about 8 minutes and 12 seconds.

Solved correctly.
