How do you solve a word problem using systems of equations?
How do you set up a system of equations from a word problem?
How do you check your answer to a system of equations word problem?
How do you solve a word problem about swimming with an against a current?
Is there an easy way to find the rate of a water current?
If a dolphin swimming against an ocean current traveled 60 miles in 2 hours and traveled back home in 1.5 hours, what is the speed of the dolphin in still water and what is the rate of the current?
How do you solve the system of equations 2(d - c) = 60 and 1.5(d + c) = 60?

This problem is very similar to the rate of a plane in the wind problem. All steps of this problem are explained. You will learn how to think about rate of current problems, how to make a table and set up equations, how to solve systems of equations, and how to check your solution in the original problem. Another great lesson.
