Estimate journey time from distance, speed and stops.
Effective speed falls well below cruising speed once stops and traffic are included. On a long drive two twenty-minute stops cost more time than a ten kilometre per hour speed difference. Estimating arrival from cruising speed alone is why journeys routinely run an hour longer than planned.

Total time = distance ÷ speed × (1 + traffic allowance) + stop time
