Marissa can paddle her kayak 4 miles per hour in still water. It takes her as long to paddle 3.5 miles upstream as it takes her to travel 24.5 miles downstream. Determine the speed of the river's current. Enter an equation with the following properties: 1. It uses the variable c to represent the speed of the river's current in miles per hour. 2. It uses the information as it is given above. 3. It can be solved to answer the question. Equation: How fast is the river's current? 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.
