Soal kelas 6

1. volume .....liter
debit 8 m3/menit
waktu 2 1/2 menit

2. volume 225 dm3
debit 15 dm3/menit
waktu .....jam

3. volume 150 liter
debit 5 liter/menit
waktu.....jam

4. 2.000 dm3
debit 125 dm3/menit
waktu .....detik

Answer 1

1) volume = 2,5 × 8 × 1000 = 20.000 liter
2) 225 ÷ 15 = 15 menit = 1/4 jam
3) waktu= 150 ÷ 5 = 30 menit = 1/2 jam
4) 2000 ÷ 125 = 16 menit = 960 detik

Answer 2

1.Diket:
debit= 8 m^3/menit=8.000 l/menit
t=2,5 menit
Ditanya: V=....?
Jawab: v= debit . t
v= 8.000 m^3/menit . 2,5 menit
v=20.000 m^3

2.Diket:
v=225 dm^3
debit=15 dm^3/menit
Ditanya: t=....?
Jawab:
t= V/debit
t= 225 dm^3/ 15 dm^3 .  1/60 jam
t= 225 dm^3/ 0,25 dm^3/jam
t=22500 dm^3/25 dm^3/jam =900 jam.

3.Diket:
v=150 liter
debit=5 l/menit→5 . 1/60 jam →0,083 l/jam
t= V/debit
t=150 l/:0,083 l/jam
t= 150.000 l: 83 l/jam
t=1807,2 jam

4.Diket:
v=2.000 dm^3
debit=125 dm^3/menit →750 dm^3/s
t=V/debit
t=2.000 dm^3 : 750 dm^3/s
t=2,67 s
