## How to solve rate of change word problems

And then our total time we can figure out. They tell us the time to the store. And then we can figure out the distance from the store and using that and the speed to figure out her time back. And then we get total distance divided by total time-- 12 miles per hour. Rates of Change. Simply defined, a rate of change is the relationship between two numbers or quantities and how they change in relationship to each other. Similar to ratios, as discussed above, rates of change are expressed as ratios and fractions, but with some measure of change in addition to the numbers that are used in a ratio. To solve rate word problems, knowledge of solving systems of equations is necessary. Rate word problems include problems dealing with rates, distances, time and wind or water current. Other types of word problems using systems of equations include money word problems and age word problems. A rate problem is usually a word problem where two variables are defined and a third variable is asked for. Some rate problems become more complicated by comparing two rates, thus doubling the number of variables. All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T). This is one of the more difficult parts of solving calculus word problems. It’s also one of the most important. Having a solid understanding of calculus, particularly the fact that derivatives represent the rate of change of the equation, will help you when creating the necessary equations. Looking for an easy way to solve rate-of-change problems? Use the chain rule!
