A cyclist managed to ride 5 miles against the wind in the same time that it took him to 10 miles with the wind. If the wind speed is 4 mph, which equation can be used to calculate the cyclist's average rate of speed in miles per hour?
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.
