Rational Equations and Press Work

The video tutorial explains how to solve a problem involving two printing presses with different speeds. It begins by organizing the given information into a table, then sets up a rational equation based on the rates of work. The tutorial walks through solving the equation, including clearing fractions and factoring a quadratic equation, to find the time each press takes to complete the job alone. The solution reveals that press number two takes 12 hours, while press number one takes 24 hours.
