Dave and sandy hartcraft are frequent flyers with a particular airiline. They often fly from city A to city B, a distance of 828 miles. On one particular trip, they fly into the wind, and the flight takes 2 hours. The return trip, which the wind behind them, only takes 1 in a half hours. If the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air. The wind speed is ?
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.
