Rational equation word problems distance, Motion Word Problems with Rational Expressions Another common application of rational expressions involves motion problems. d = rt Let's look at an example. In this section, the applications will often involve the key word “reciprocal. For example, the reciprocal of 5 is 1 5 and 5 1 5 = 1. Recall the distance formula relates the distance traveled (d) to the rate of speed (r) times the time traveled (t). Example 2: Solve each word problem. Distance, rate and time problems are a standard application of linear equations. Example 3: Solve each word The topics include, but are not limited to, linear equations and inequalities, operations with polynomials, data representation, and analysis, geometric constructions, symmetry, similarity, systems of linear equations and inequalities, functions, quadratic equations, exponential equations, rational equations, radical equations, and graphing Khan Academy Sign up. Strategy for Solving Word Problems problem careful, sometimes Let a variable represent the unknown information, and represent every else in terms of it If possible/necessary make a diagram or drawing Write an equation relating your unknown quantities to what you are given Solve the equation Motion Word Problems with Rational Expressions Earlier in our course, we learned how to use the distance formula when working with motion word problems. These problem types were studied earlier in algebra and involve our distance formula: d = r • t Where d is the distance, r is the rate of speed, and t is the time.
