7. 8.000.000 km=.....mm
tolong dijawab yaaa butuh,pakek cara ya

Answer 1

1. 50x1000m / 1x3600s
= 50000/3600 m/s hasil nya itung aja
2. 250km = 250x1000m
=250000 m
3. 85000 m = 85000 x 1/1000 km
= 85 km
4. 250.000.000 m = 250.000.000 x 1/1000
= 250.000 km
5. 15 mnt = 15.60 detik
=900 detik
6. 7200000 detik = 720000 : 3600 jam
= 200 jam
7. 8000000km = 8.000.000 x 1000.000
= 9000.000.000.000 mm
note:
km > hm > dam > m > dm > cm > mm
turun 1 (kekanan) = x1/10
naek (kekiri) = x10
1 jam = 60 mnt = 3600 detik
1 mnt = 60 detik
