marfaaudilla1916.) volume = p x l x t = 80 x 50 x 50 = 200.000 cm³ = 200 liter debit = volume : waktu volume = 200 - 50 = 150 = 150 : 20 = 7,5 dm³/menit ( C)
18.) waktu = jarak : kecepatan jarak = 15 km kecepatan = 45 km = 15 : 45 =15/45 jam = ....menit = 15/45 x 60 = 20 menit waktu = 20 menit = 08.15 + 20 menit = 08.35 ( D )
debit = volume : waktu
volume = 200 - 50 = 150
= 150 : 20
= 7,5 dm³/menit ( C)
18.) waktu = jarak : kecepatan
jarak = 15 km
kecepatan = 45 km
= 15 : 45 =15/45 jam = ....menit
= 15/45 x 60 = 20 menit
waktu = 20 menit
= 08.15 + 20 menit
= 08.35 ( D )
