Enter the distance to the incident and the average speed of the response vehicle into the calculator to determine the response time. This calculator helps in planning and estimating the time required for emergency services to reach a location.

Response Time Formula

The following formula is used to calculate the response time.

RT = D / S

Variables:

  • RT is the response time (hours)
  • D is the distance to the incident (miles)
  • S is the average speed of the response vehicle (miles per hour)

To calculate the response time, divide the distance to the incident by the average speed of the response vehicle.

What is Response Time?

Response time is the duration it takes for emergency services or a response vehicle to reach the scene of an incident from the time the incident is reported. It is a critical factor in emergency situations where immediate action is required to prevent further damage or loss of life. The response time can be influenced by various factors including the distance to the incident, the speed of the response vehicle, traffic conditions, and the efficiency of the emergency response system.

How to Calculate Response Time?

The following steps outline how to calculate the Response Time.


  1. First, determine the distance to the incident (D) in miles.
  2. Next, determine the average speed of the response vehicle (S) in miles per hour.
  3. Next, gather the formula from above = RT = D / S.
  4. Finally, calculate the Response Time (RT) in hours.
  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 to the incident (D) = 60 miles

average speed of the response vehicle (S) = 45 miles per hour
