108. Comparing wind chills. Use the formula from
Exercise 107 to determine who will feel colder:
a person in Minneapolis at 10°F with a 15-mph wind
or a person in Chicago at 20°F with a 25-mph wind.
94. Sharing cost. The members of a flying club plan to share
equally the cost of a $200,000 airplane. The members
want to find five more people to join the club so that the
cost per person will decrease by $2000. How many members
are currently in the club?
...Chill(oF) = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16
T= air temp oF
V = wind speed mph
So for the first scenario, V = 15, T = 10 Wind Chill = -6.59°F
So for the first scenario, V = 15, T = 10 Wind Chill = 2.64°F
Minneapolis is ...
