This lesson covers how to solve a rate-time-distance word problem when only the distance is known. The problem is solved using one variable and using the fact that time equals distance divided by rate. The problem is then solved using a rational equation and quadratic equation. The lesson provides step-by-step instructions on how to solve the problem and includes a helpful visual aid.
