A unit rate compares a quantity to its unit of measure.
How to solve distance rate and time. In some cases you will not need to bottom row but I always make the same chart to begin each problem even if I dont need to bottom row. Distance rate and time problems are a standard application of linear equations. Together we will look at five examples in detail for how to solve Distance-Rate-Time word problems.
A unit price is a rate comparing the price of an item to its unit of measure. If rate r is the same as speed s r s dt. Distance speed x time Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour.
To find the total distance multiply rate times time or 30kmh 4h 120 km. To solve for distance use the formula for distance d st or distance equals speed times time. When solving distance problems we will use the relationship rt d or rate speed times time equals distance.
For example if a person were to travel 30 mph for 4 hours. Problems using this type of rate can be solved using a proportion or a formula. If students are struggling explain that to solve these problems they will apply the formula that solves distance rate and time which is distance rate x tim e.
To solve distance rate ti. To find the total distance we would multiply rate times time or. Distance Rate Time How-To Video.
Distance Rate and Time Calculator. For example suppose a person were to travel 30 kmh for 4 h. I always create a 3 by 3 chart and label the left side based on the problem at hand the last row is always labeled Total.
One cyclist rides twice as fast as the other. Create a Distance Rate and Time chart similar to the one shown below. Use the formula r dt.
The math to calculate the distance might look like this. If they arent youll need to change them so youre working with the same units. An application of linear equations can be found in distance problems.
R 24 miles 2 hours 12 miles per hour. Before you can use the distance rate and time formula DRT you need to make sure that your units for the distance and time are the same units as your rate. Two cyclists start at the same corner and ride in opposite directions.
