vCalc.Time to Overtake

The Time to Overtake calculator computes the amount of time needed to overtake a vehicle based on the speeds of the two vehicles and the head start.

INSTRUCTION: Choose units and enter the following:

  • (h)  Distance between the vehicle (i.e. the head start)
  • (V1) This is the velocity of the chase vehicle.
  • (V2) This is the velocity of the lead vehicle.

Time to Overtake (t): The calculator returns the time in minutes.  However, this can be automatically converted to compatible units via the pull-down menu.

The formula for the time required to overtake is:

        t = h / (V1 - V2)


  • t is the time required at the specified velocities for vehicle 1 to overtake vehicle 2.
  • h is the distance between the vehicles or the head-start.
  • V1 is the velocity of vehicle one
  • V2 is the velocity of vehicle two.
