What's the Formula Connecting Distance, Speed, and Time?
Definition: What is the formula for uniform motion?
Summary
- 'Uniform motion' means we have an object traveling at a constant speed
- 'd' is a variable that represents distance
- 'r' is a variable that represents rate
- 't' is a variable that represents time
- The distance is unknown
- The rate is 500 miles per hour
- The time is 3 hours
- The distance equals 500•3
- The plane traveled a distance of 1500 miles

Notes
-
-
- d, r, and t are the variables in our formula
- The d stands for distance
- The r stands for rate
- The t stands for time
- So distance equals rate times time
-
-
-
-
-
- In this example we are looking for DISTANCE, which is represented by 'd'
-
-
-
- 'd' is our unknown
-
-
- 500 mph is the rate the plane is flying
-
-
- 3 hours is the time spent traveling
-
-
- d=500•3
-
- 500•3=1500
-
- Our units will be miles, because our rate was measured in miles per hour

- Our units will be miles, because our rate was measured in miles per hour
