Perhitungan ETA
Rumus :
Jarak = waktu tiba
Speed
Atаu
Jarak + jam perhitungan x 60 (1 jam)
Speed
Cоntоh soal :
Tgl 26 Jam : 19.00
Jarak ke….. 1089 mile
Speed = 9,5 knot
Hitung ETA ? (tanggal , jam )
1089 = 114,6 x 19.00
9,5
= 3046 x 60
= 18.27
26
5
Tgl 31 jam 18.27
Jarak : speed x waktu LT = hasil : 24 = hasil (hari)
Harinya x 24 =
Jam….. menit…. Detik
Example : 1.
Jarak : 603 miles
Speed : 10,5 knots
Waktu tolak : 20.00
603 : 10,5 = 57,428571 + 20.00 = 77,428571 : 24 =
3,2261905 – 3 = 0,2261905 x 24 =
5,4285714 = 5º 25,6’ – 5 = 3d 5h 25,6m
Example : 2.
Ujung pandang → tanjung priok = 769 miles
Speed = 11 knots
769 = 69,9
11
69,9 = 2,91 → 2 hari
24
0,91 x 24 = 21,81 → 21 jam
0,81 x 60 = 48,6 → 48,6 menit
Kalau kurаng dаrі 24 jam x 60 = ….. dі dapat menitnya
