1. 3m/detik=…km/jam 2. 10,8km/jam =…m/detik aku kasih 50 poin deh pakai cara ya

Jawaban:

1. 3 m/detik = …. km/jam

1 km = 1.000 m

1 jam = 3.600 detik

3 m = 3 ÷ 1.000 = 0,003 km

0,003 km × 3.600 detik

= 10,8 km/jam

2. 10,8 km/jam = …. m/detik

10,8 km = 10,8 × 1.000 = 10.800 m

10.800 m ÷ 3.600

= 3 m/detik

kalo salah jangan di maafin.

Jawaban:

1. 3m/ detik

=0,003 km / 1/3600 jam

= 3/1000 km / 1/3600 jam

=3/1000 km • 3600 jam

= 10,8 km/jam

2. 10,8km/jam

= 108 000 : 3600

= 30 m/detik
