A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 hour and 48 minutes. What is the plane's speed in still air, and how fast is the wind blowing? HINT: If one of the times includes minutes, first, change minutes to hours by dividing by 60. Use the resulting decimal for time when setting up equations his plane speed equals mph. the wind speed equals mph
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
