## How to Solve Rate Problems | Sciencing

"I rate my problem-solving skills as an 8/ I will, on occasion, have times when I am not as efficient as I would like to be but all in all, I do feel that my problem-solving skills are above average. My supervisor and co-workers will attest to my fast reflexes when a problem arises, and they would also say that I remain calm under pressure."Author: Rachelle Enns. Apr 24, · 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). Rate problems are basically easy but you have to make sure you keep the units straight. That's because rate problems involve a lot of multiplying and dividing. For example, if a guy travels km in 20 hours, we find out his speed by dividing km by 20 hours to get 25 km/hour.

## Solving Problems With a Distance-Rate-Time Formula

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. Read the problem and identify which of the two things' rates are being compared. If more than two rates are involved, draw additional rows as necessary, **rate problem solving**. If one rate is mentioned, just use the first row.

Label each *rate problem solving* in the first column with the name of the **rate problem solving.** Convert any given numbers to be in matching units.

If one speed is in miles per hour and another is in feet per second, pick which unit you want to work with and convert the other amount to use that unit.

Plug any given numbers into the grid. Create a variable for any missing figures. Use "d" for distance, "r" for rate and "t" for time. Circle the part of the grid the question is asking for. This is the variable you eventually want to solve for. Simplify each equation as much as possible. If only one variable is present, *rate problem solving*, solve for it using basic algebra.

Plug in any solved variable to solve further. If you haven't reached your answer in Step 2, take any solved variable and insert it into the other equation, then keep solving.

Label the columns in the first row with "Name," "Distance," "Rate" and "Time. Photo Credits.
