Enter the distance and speed into the calculator to determine the time it takes for an object to travel a certain distance. This calculator can also evaluate any of the variables given the others are known.

Fast Time Formula

The following formula is used to calculate the time it takes for an object to travel a certain distance at a given speed.

 T = D / S


  • T is the time it takes to travel the distance
  • D is the distance to be traveled
  • S is the speed at which the object is traveling

To calculate the time it takes to travel a certain distance, divide the distance by the speed at which the object is traveling.

What is a Fast Time?

Fast Time is a term often used in aviation and simulation industries to refer to the acceleration of time in a simulation or training scenario. This allows for the simulation of long-duration events in a shorter period of time. For instance, a flight simulation that would normally take several hours can be completed in a matter of minutes using Fast Time. This is achieved by increasing the speed at which the simulation runs, effectively compressing the time scale. It is particularly useful in testing and training scenarios where real-time operation is not necessary or practical. It allows for the efficient use of time and resources, enabling the observation and analysis of events that occur over a long period in a much shorter time frame.

How to Calculate Fast Time?

The following steps outline how to calculate the Fast Time.

  1. First, determine the distance traveled (d) in miles.
  2. Next, determine the speed (s) in miles per hour.
  3. Next, gather the formula from above = Fast Time = d / s.
  4. Finally, calculate the Fast Time.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

distance traveled (d) = 150 miles

speed (s) = 60 miles per hour
