Question

1.54km/jam=......m/detik.tolong dibantu pake caranya.
2.200cm/detik=........km/jam.tolong dibantu pake caranya.
3.108.00liter/detik=.........m³/jam.tolong dibantu pake caranya

Answer 1

1. 54km/jam = ... m/ detik
= 1 km = 1000 m
= 1 jam = 3600 detik
= ( 54 km x 1000 ) / 3600 detik
= 54000 m / 3600 detik
= 15 m / detik

2. 200cm / detik = ... km / jam
= 1 km = 100000 cm
= 1 jam = 3600 detik
= ( 200 : 100000 ) / 1/3600
= 0,002 km / 1 / 3600
= 0.002 x 3600
= 72 km / jam


3. 10.800 l / detik = ... m^3 / jam
= 1 l = 1 dm
= 1 m^3 = 1000 dm^3
= 1 jam = 3600 detik
= (10.800 : 1000 ) / 1/3600
= 10,8 m^3 / 1/3600
= 10,8 m^3 x 3600
= 38.880 m^3 / jam

( maaf ya kalo slh ^.^ )

Answer 2

1) 54 km/jam = 54 x 1000/ 3600 m/detik = 15 m/detik
2) 200 cm/detik = 200 / 100000 x 3600 km/jam = 7,2 km/jam
3) 108 liter/detik = 108 x 3600 m^3/ jam = 388800 m^3/jam
