1.) 20 m/detik = …… km/jam 2.) 0,12 liter/detik =…… m3/menit

1.
20 m/detik
= 20 ÷ 1000 km/1 ÷ 3600 jam
= 20/1000 × 3600
= 72 km/jam

2.
0,12 liter/detik
= 0,12 ÷ 1000 m³/1 ÷ 60 menit
= 3/25000 × 60
=180/25000
= 9/1250 m³/menit = 7,2 × 10^-3 m³/menit

Saya coba bantu yah !

1). 20 m/detik = ..... km/jam

Perlu di ingat :
1 m = 1/1000 km
1 jam = 3600 detik
1 detik = 1 / 3600 jam

Maka,
= 20 m/detik
= [20 (1/1000)] / (1/3600)
= 2/100 × 3600/1
= 2 × 36
= 72 km/jam

2). 0,12 liter/detik = ..... m³/menit

Perlu di ingat :
1 liter = 1 dm³
1 dm³ = 1/1000 m³
1 menit = 60 detik
1 detik = 1/60 menit

Maka,
= 0,12 liter/detik
= 0,12 dm³/detik
= [0,12 (1/1000)] / (1/60)
= 0,12/1000 × 60/1
= 7,2/1000
= 0,0072 m³/menit
atau
= 7,2 × 10⁻³ m³/menit

Semoga bisa membantu yah
