Science experiment

During a Science experiment, a liquid was heated at the rate of 8 degrees Celsius per minute for 10 minutes. It was then allowed to lose heat at 6 degrees Celsius per minute. If the final temperature was 76 degrees Celsius, what was its temperature 16 minutes ago?

Correct answer:

t =  52 °C

Step-by-step explanation:

s1=8 °C/min s2=6 °C/min a=10 min b=1610=6 min  t=76+s2 bs2 a=76+6 66 10=52°C
