Just before midnight, the first musher, William “Wild Bill” Shannon, left Nenana. It was -50ºF. When he took his first break, it was 12º colder. What was the temperature?
Getting colder means there was temperature reduction (ie the hotter the temperature the higher its value and the colder the temperature the lower its value) Hence the temperature was = -50 - 12 = -62 °F
