Question 184385:
DONT DO THIS ONE 107. Wind chill. The wind chill temperature W (how cold the air feels) is determined by the air temperature t and the wind velocity v. Through experimentation in Antarctica, Paul Siple developed a formula for W: W: W=91.4-(10.5+6.7Sqrt(x)v-0.45v)(457-5t)/110 , where W and t are in degrees Fahrenheit and v is in miles per hour (mph).
a) Find W to the nearest whole degree when t =25°F and v=20 mph.
b) Use the accompanying graph to estimate W when t = 25°F and v = 30 mph.
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.
