50km/jam =400km/8jam, 30km/27mistirahat selama 80m=1jam20m
07.30+9jam47m =18.10 jadi mutiara sampe pukul 18.10
=> waktu = jarak / kecepatan
Diketahui :
Jarak = 430 km
Kecepatan = 50 km/jam
Waktu = jarak / kecepatan
= (430 / 50) jam
= (43/5) jam
= (43/5) . 60 menit
= 43 . 12 menit
= 516 menit
= 8 jam 36 menit
Istirahat = 80 menit
= 1 jam 20 menit
Berangkat pukul 7.30, maka mutiara sampai pada pukul
= 7.30 + 8 jam 36 menit + 1 jam 20 menit
= (7 + 8 + 1).(30 + 36 + 20)
= 16.86
= 17.26
