the temperature of a liquid decreasing at a constant rate. after two minutes of cooling, it was at 178 degrees and after five minutes of cooling it was at 154 degrees. at what temperature did the liquid start cooling. NEED STEP BY STEP EXPLANATION

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
