To Estimate the Number of Hours T That a Murder $t = \frac { 1 } { 0.25 } \ln \frac { 98.6 - T _ { s } } { 82 - T _ { s } }$

Short Answer

To estimate the number of hours t that a murder victim had been dead, a coroner used the formula $t = \frac { 1 } { 0.25 } \ln \frac { 98.6 - T _ { s } } { 82 - T _ { s } }$ where $T _ { s }$ is the temperature of the surroundings where the body was found. If the crime took place in an apartment where the thermostat was set at $74 ^ { \circ } \mathrm { F }$ , approximately how long ago did the murder occur?
Please round the answer to one decimal place. about __________ hours ago
