When working on Distance-Rate-Time questions, you will inevitably use one of the following three formulas.<\/p>\n
1. Distance = (Rate)(Time)<\/p>\n
2. Rate = Distance\/Time<\/p>\n
3. Time = Distance\/Rate<\/p>\n
Did you know that there\u2019s a quick and easy shortcut for recalling all three formulas?<\/p>\n
The shortcut is similar to some of the shortcuts you learned in highschool science. It looks like this:\u00a0 D\/RT (aka, the \u201cDiRT\u201d shortcut).\u00a0 As you may have guessed, D = distance, R = rate, and T = time.<\/p>\n
Can you see all three formulas hiding in the simple fraction D\/RT?<\/p>\n
Here\u2019s how it works. Let\u2019s say, you need to recall the formula for finding the time it takes to complete a certain trip. Simply take the fraction D\/RT and remove the T (for time). This leaves you with D\/R. In other words, Time = Distance\/Rate.<\/p>\n
Similarly, if you need to recall the formula for finding the rate (speed), simply take the fraction D\/RT and remove the R (for rate). This leaves you with D\/T. In other words, Rate = Distance\/Time.<\/p>\n
Finally, if you need to recall the formula for finding the distance, take the fraction D\/RT and remove the D (for distance). This leaves you with RT. In other words, Distance = (Rate)(Time).<\/p>\n
So, instead of memorizing 3 formulas, just remember DiRT, which stands for D\/RT.<\/p>\n
