Three runners start at the same location and, at the same time, start running in different directions. Runner A runs west at 10 mi/hr, Runner B runs north at 12 mi/hr, and Runner C runs east at a non-constant speed. If, after 15 minutes, Runner C has traveled 2.25 mi and the area of the triangle formed by the three runners is changing at a rate of 60 mi2 /hr, find the speed of Runner C at this time. must show all steps
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.
