Your best friend is adamant about competing in a mini-triathlon that consists of first a 2km endurance run, then a 2km hilly cycling, and lastly a 2km freestyle swim. She wants YOU, the mathematics expert, to design a guideline for her training. You determined that, to have a shot at winning, she must maintain an average speed of 5 km/h throughout the entire triathlon. She must run at 15 km/h and cycle at 30 km/h. What should be her swimming speed if she is to have a shot at winning?
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.
