2) 18 Km/jam= M/detik
3) 9 m/detik= Km/jam
pliss kak jawab bsk dikumpul
1) 4 Km/jam = M/detik
Jawab
1) 1 1/9 m/detik
2) 5 m/detik
3) 32,4 km/jam
Penjelasan dengan langkah-langkah:
1) 4km = 4000 m
1jam = 3600 detik
= 4000/3600
= 40/36
= 10/9
= 1 1/9 m/detik
2) 18km = 18000 m
1jam = 3600 detik
= 18000/3600
= 180/36
= 5 m/detik
3) 9m = 0,009 km
1 detik = 1/3600 jam
= 0,009 ÷ 1/3600
= 9/1000 × 3600/1
= 9/10 × 36/1
= 324/10
= 32,4 km/jam
