Let us take a look at some simple examples of distance, time and speed problems. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed. It is abbreviated as: There are many examples where you might use this formula in real life. How far away from Deb's house will the faster train pass the other train? Remember the formula: When identifying the parts of the word problem, distance is typically given in units of miles, meters, kilometers, or inches. Distance is the length of space traveled by a moving object or the length measured between two points. Rate is distance per time, so its units could be mph, meters per second, or inches per year.

To solve the problem, remember that d represents the distance in miles from Deb's house and t represents the time that the slower train has been traveling. The second train finally caught up with the first train after traveling for three hours. It is usually denoted by r in equations. Once you read the problem, simply plug the numbers into the formula. Organize the information you have in a chart format if you haven't solved these types of problems before. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. You will also apply the formula that solves distance, rate, and time, which is distance = rate x time. This topic includes [[feature_name]], available only on desktop and/or tablet. With Creative Coding, you can connect computer programming to any subject. Two hours later, another train leaves from Deb's house on the track beside or parallel to the first train but it travels at 100 mph. Tim and Moby figure it out. Speed = Distance Time, \mbox{Speed} = \frac{\mbox{Distance}}{\mbox{Time}}, Speed = Time Distance , which can also be rearranged as.
