Solve the problem.
-It took 28 seconds for the temperature to rise from $9 ^ { \circ } \mathrm { F }$ to $167 ^ { \circ } \mathrm { F }$ when a thermometer was taken from a freezer and placed in boiling water. Although we do not have detailed knowledge about the rate of temperature increase, we can know for certain that, at some time, the temperature was increasing at a rate of $\frac{79}{14}^ {\circ}$F/sec.
Explain.
