Hari 1

Kerja kotor = 06.00 – 17.00 = 11 jam

Istirahat = 50 menit (mesin menyala)

Setting up = 25 menit (mesin mati)

Kerja bersih = 9 jam 45 menit = 585 menit

Maka harga bensin :

Kerja 585 menit (6liter/jam) = 58.5 liter

Istirahat 50 menit (2 liter/jam) = 5/3 liter

Maka : 585.5 liter + 5/3 liter = 361/6 liter x Rp.6.900,00/liter = Rp. 415.150,00

Total pengeluaran hari ke-1

Bahan bakar = Rp. 415.150,00

Operator = Rp. 90.000,00

Uang makan = Rp. 20.000,00

Total = Rp. 525.150,00

Mencari jarak :

Kerja kotor = 06.00 – 17.00 = 11 jam

Istirahat = 50 menit (mesin menyala)

Setting up = 25 menit (mesin mati)

Kerja bersih = 9 jam 45 menit = 585 menit

t = 35100 sekon

v = 7.2 km/jam

v = 7200/3600 = 2 m/s

v = s/t

2 m/s = s / 31500 s

s = 71.200 m

s = 71.2 km
