Assignment:
W = 91.4- (10.5 + 6.7v-0.45v)(457 - 5t),
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.
Comparing wind chills. Use the formula from above 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.
Provide complete and step by step solution for the question and show calculations and use formulas.
