Distance : 1098km
- 1077km autoroute à 130km/h
- 21km route à 80km/h
Réservoir : 47L
Consommation : 5L/100km
Prix/L carburant : 1,35€
Pause : 15min/2h
Vitesse = Distance/Temps
Temps = D/V
T(autoroute) = 1077/130 = 8,28h
T(route) = 21/80 = 0,2625h
T(total sans pause) = 8,28+0,2625 = 8,5425h
8/2 = 4 pauses de 15min
4×15 = 60min = 1h
T(total avec pause) = 8,5425+1 = 9,5425
0,5425×60 = 32,55 min
0,55×60 = 33s
T(total) = 9h32m33s
Distance = 1098km
5L/100km
1098/100 = 10,98
10,98×5 = 54,9L
total dépenses carburant = 54,9×1,35 = 74,115€
cout peage = 87,80€
Total dépenses = 74,12+87,80 = 161,92€
