Tolits is working on a restaurant famous for its bulalo soup. His end of shift is 5:00 pm
and needs to go home by that time to pick up his wife, Marites for their anniversary
date. A customer made a reservation at 5:15 pm and wants his bulalo soup to be ready
at that exact time. To ensure the quality of the soup, it should be served at a
temperature which is exactly 82
C. Tolits needs to prepare the bulalo before the end of his shift. Initially, as Tolits is
preparing the bulalo soup, its temperature is 23
C and placed on a pan heated at 153
C. After 5 minutes, its temperature is 34
C. The bulalo soup is done (cooked) once its temperature is 120
C. Tolits found out that cooling it in a sink full of cold water, while the faucet is running
with the water resulting to roughly constant temperature of 25

with the water resulting to roughly constant temperature of 25
C, could bring the temperature of the bulalo to 82
C to be ready at 5:15 pm. How many minutes before the end of the shift of Tolits should
he start cooking bulalo so that he is done before 5:00 pm and his co-worker can serve it
at 5:15pm?
