Should average speed include stops? Decide what the estimate is for
Moving average speed and departure-to-arrival average speed describe different intervals. A journey budget usually needs more than the speed while moving.

Covering 120 km in two hours of movement gives a moving average of 60 km/h. Add a thirty-minute break and total elapsed time becomes 2.5 hours, so the whole-trip average is 48 km/h. Both figures can be valid, but they answer different questions. Label the time basis when comparing them.
Keep the calculation internally consistent
To estimate arrival, either use an average-speed assumption that includes planned stops or calculate moving time and add the stops separately. Do not use an already stop-inclusive average and then add the same break again. The time converter can turn two hours thirty minutes into 2.5 hours before the value is entered.
Do not turn a numerical target into driving advice
The speed tool does not include road limits, traffic or weather and cannot determine a safe driving speed. Leave practical contingency in a travel plan rather than trying to achieve a computed average by speeding. The same timing distinction matters for running pace: moving time and complete elapsed time can produce different averages. Preserve the distance and both time records where available so the choice can be reviewed instead of hidden inside one displayed speed.
