hrust $,1-97E$ The average body temperature of a person rises by about $2C$ during strenuous exercise. What is the rise in the body temperature in $(a)K,(b)F,$ and $(c)R$ during strenuous exercise?

$1-98$ The average temperature of the atmosphere in the world is approximated as a function of altitude by the relation

$T_{\text{a}\text{t}\text{m}}=288\mathrm{.}15-6\mathrm{.}5z$

where $T_{\text{a}\text{t}\text{m}}$ is the temperature of the atmosphere in K and $z$ is the altitude in km with $z=0$ at sea level. Determine the average temperature of the atmosphere outside an airplane that is cruising at an altitude of $12,000m.$
