`t = h/(V_1-V_2)`

Enter a value for all fields

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 Vehicles (i.e. the head start)
• (V₁) Velocity of Chase Vehicle
• (V₂) Velocity of 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 calculator also returns the distance V₁ will have to travel to overtake.

Related Calculators

• Time to Overtake: Computes the distance in which the overtake will occur at constant velocities.
• Distance to Overtake: Computes the distance in which the overtake will occur at constant velocities.
• Speed to Overtake before a Distance: Computes the speed required to intercept within a distance boundary.
• Speed to Overtake in Time: Computes the speed required to intercept within a time boundary.

The Math / Science

The formula for the time required to overtake is:

        t = h / (V₁ - V₂)

where:

• t = Time required for vehicle 1 to overtake vehicle 2.
• h = Distance between the vehicles or the head-start.
• V₁ = Velocity of vehicle one
• V₂  = Velocity of vehicle two
