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) - (
**V**) Velocity of Chase Vehicle_{1} - (
**V**) Velocity of Lead Vehicle_{2}

**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 V_{1} will have to travel to overtake.

- 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 formula for the time required to overtake is:

t = h / (V_{1} - V_{2})

where:

- t = Time required for vehicle 1 to overtake vehicle 2.
- h = Distance between the vehicles or the head-start.
- V
_{1}= Velocity of vehicle one - V
_{2}= Velocity of vehicle two.

The US** Mileage Rate for Business Travel **shows the dollars per mile deduction for business travel for the calendar year. The most recently queried information from the IRS website on mileage includes:

Mileage Calendar Year: 2022

- $62.5 USD/mi: Mileage Deduction for Business Travel
- $22.0 USD/mi: Mileage Deduction for Moving or Medical Travel
- $14.0 USD/mi: Mileage Deduction for Charitable Donation Travel

Use these deductions rates in the Mileage Tax Deduction Calculator. It computes tax deductions from miles travelled. Just enter the miles traveled and see the dollar amount associates for business, moving or medical, and charitable work.

International travel poses a several challenges, even if it's just over the boarder to Canada or Mexico. First, there is the conversion from liters to gallons, which is fixed, and then there's the conversion between the US dollar and other currency, which is constantly changing. vCalc is here to help. We know how to do the math and we keep track of currency fluctuations, and the result makes it easier on you.

Here are four examples, US dollar per gallon from

- Euros per Liter
- Canadian Dollars per Liter
- Great Britain Pounds per Liter
- Mexican Pesos per Liter

The formula to convert Euros per Liter to U.S. Dollars per Gallon is:

`DPG = € EPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "€ 0.952 EUR")`

The formula to convert Canadian Dollars per Liter to U.S. Dollars per Gallon is:

`DPG = Can$ CPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "$ 1.358 CAD")`

The formula to convert Great Britain Pounds (Sterling) per Liter to U.S. Dollars per Gallon is:

`DPG = £ PPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "£ 0.82 GBP")`

The formula to convert Mexican Pesos per Liter to U.S. Dollars per Gallon is:

`DPG = ? PPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "?19.731 MXN")`

where:

- DPG = US Dollars per Gallon
- € EPL = Euros per Liter
- Can$ CPL = Canadian Dollars per Liter
- £ PPL = Pounds per Liter
- ? PPL = Pesos per Liter
