Quick guide

How to use this calculator

  1. Choose the real journey or motion relationship first, then enter only the measurements that belong to that mode.
  2. Keep every distance, speed, duration, clock, direction, break, reserve, wind, or current convention explicit; the calculator normalizes compatible units internally.
  3. Use the companion outputs to reconcile the scenario, then retain the stated limits before using an estimate for a real journey.

Calculation method

How the journey time scenario comparator works

Show the nonlinear time effect of different average-speed and stop assumptions while preserving every scenario for comparison.

For each scenario, elapsed time = normalized common distance ÷ normalized average speed + that scenario’s breaks. Differences are measured against the fastest entered scenario.

Worked example

Journey Time Scenario Comparator example

For 300 km, 90 km/h plus 30 minutes takes 3 hours 50 minutes, while 70 km/h plus 45 minutes takes about 5 hours 2 minutes.

For each scenario, elapsed time = normalized common distance ÷ normalized average speed + that scenario’s breaks. Differences are measured against the fastest entered scenario.

Supported inputs

Precision and limits

Scenario boundary

Scenario speeds are visitor-entered averages, not recommendations or legal limits. No live traffic, route, weather, safety, emissions, fuel cost, or optimization data is inferred.

Precision and time

Calculations retain working precision and round durations to the nearest second and clock outputs to the nearest minute. Entered averages and schedules remain assumptions, not live observations or guarantees.
