How a Car Trip's Fuel Cost Is Calculated

A trip's fuel cost comes from two simple divisions and a multiplication — distance divided by mileage gives the liters needed, and multiplying that by the fuel price gives the total cost.

How a Road Trip's Total Cost Is Estimated

A road trip's total cost adds fuel cost (distance divided by mileage, times fuel price) to tolls and food/lodging spread across the trip's days — three separate expense categories added together into one figure.

How to Calculate Driving Time From Speed and Distance

Estimating driving time only requires dividing the trip distance by the average speed you expect to maintain, but the accuracy of that estimate depends entirely on how realistic the speed figure is for the actual route, not just the number itself.

How to Calculate Trip Distance From Speed and Time

Working out how far you can travel in a given amount of time only requires multiplying your average speed by the time available, the reverse direction of the more commonly asked "how long will this trip take" calculation.

Understanding the Speed, Distance, and Time Formula

Speed, distance, and time are linked by one formula — distance equals speed multiplied by time — but that single relationship can be rearranged three different ways depending on which of the three values you already know and which one you're solving for.
