1.09.18-06.30=2.48 menit=2,8 jam
=65 km/jam ×2,8 jam 156 km
2.217 km ÷ 62 km/jam =3,5 jam=3.30 menit
13.00+3.30=16.30
1. D = V : W
= 1800 liter : 15 menit (900 detik)
= 1800 liter : 900 detik = 2 liter/detik
2. W = V : D
= (100 cm x 60 cm x 80 cm) : 200 cm³/detik
= 480.000 cm³ : 200 cm³/detik
= 480.000 cm³ : 1200 cm³/menit
= 400 menit
3. W = V : D
= 45 liter : 0,3 liter/detik
= 45 liter : 18 liter/menit
= 2,5 menit / 2.30 (menit)
maaf kalo ada yg salah yaa :v
yg bawah dah dikerjain yg lain
