# Solve Problems Involving Rates and Ratios

Watch this video as the instructor clearly explains how to solve a word problem involving finding unit rates. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. See how you can apply this process to help you solve similar problems.

# How to use Ratios and Proportions to Solve Real World Problems

## By mrtedmartin

Instructor uses a Power Point presentation to demonstrate how to use ratios and proportions to solve problems real world problems. Unit rates are discussed and definitions are given. Solving unit rate problems are modeled and a calculator is used for computation.

# Comparing rates

Finding a unit rate is a skill often required in real life. How fast is that plane flying? How many lawns can you mow in an afternoon? You see, with our knowledge of ratios and fractions, we can now solve unit rates problems like this.

# Speed translation | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy

This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!
