James runs along the shore for a while and then jumps into the water and swims from there directly to the child. James can run at a rate of 3 meters per second and swim at a rate of 1 meter per second. How far along the shore should James run before jumping into the water in order to save the child? Round your answer to three decimal places.
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.
