Initially, the temperature of an object is 70 degrees celsius, it is taken outside. The temperature of the surrounding is 20 degrees celsius at 3:03 Pm, the temperature of the body becomes 42 degrees celsius. Later, the object is then taken back inside where the temperature is 80 degrees celsius. At 3:10 PM, the temoerature of the object is 71 degrees celsius. Determine the time when the object is brought inside.
