Part of video series Solving Systems of Equations
Taught by YourMathGal
More free YouTube videos by Julie Harland are organized at http://yourmathgal.com
Shows how to solve a word problem involving the rate of a current and rowing in still water using 2 variables and 2 linear equations.
  • 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.
