directions: read the passage, and answer the question that follows:

snag, a village located in the canadian yukon territory, has the distinction of recording the lowest temperature in north america at -62.8° c on february 3, 1947. for more than a week before that day, cold air from northeastern siberia stalled over the yukon. skies were clear, winds calm, visibility unlimited and 38 cm of snow lay on the ground. an exhaled breath of air made a hissing sound as it froze. exposed skin froze in less than 3 minutes.
convert -62.8º c into fº using the correct formula below.
conversion formulas:
cº = (fº - 32º) 1.8
fº = 1.8 x cº + 32º
k = cº + 273
