To calculate the temperature drop per day, you can divide the total temperature drop (from 175.5 degrees to 1 degree) by the number of days (3.5 days):
Temperature drop per day = \(\frac{{175.5 \text{ degrees} - 1 \text{ degree}}}{{3.5 \text{ days}}}\)
Temperature drop per day ≈ \(49.57 \text{ degrees per day}\)
So, the temperature dropped approximately 49.57 degrees per day.
