1 km = 1000 m
1 jam = 3600
Kemudian 72 km dikalikan 1000 hasilnya 72000
caranya : 72000/3600 = 20 m/s

Kecepatan satuan SI (satuan international) nya m/s 1 km= 1000 m 1 jam= 3600 s 1 km/jam = 1000m/3600s Soal: 72 km/jam= ..m/s = (72×1000)m /3600s = 72000m/3600s = 20 m/s
1 km= 1000 m
1 jam= 3600 s
1 km/jam = 1000m/3600s
Soal:
72 km/jam= ..m/s
= (72×1000)m /3600s
= 72000m/3600s
= 20 m/s
