2. 420 m/detik = … m/menit
3. 330 hm/menit = … km/jam
4. 245 cm/detik = … m/jam
5. 66.000 dm/jam = ... hm/menit.
6. 7.440 m/jam = … m/menit
7. 12 km/jam = ...cm/detik
8. 50 dm/detik = ... km/menit
9. 810 dam/menit = ...mm/detik
10. 54 m/detik = ... dam/jam
berapa gaes

Answer 1

1. 85 x 100 = 8500 dam/jam

2. 420 x 60 =25200 m/menit

3. 330/10 x 60 = 1980 km/jam

4. 245/100 x 3600 = 8820 m/jam

5. 66.000/10 x 1/60 = 110 hm/menit

6. 7440/60 = 124 m/menit

7. 12 x 100.000/3600 = 333 1/3 cm/detik

8. 50/100 x 60 = 30 km/menit

9. 810 x 10.000/60 = 135.000 mm/detik

10. 54/10 x 3600 = 19440 dam/jam

Answer 2

1.85km/jam=8.500dam/jam
km→dam=x100
=85x100=8500dam/jam

2.420m/detik=25.200m/menit
detik→menit=x60
=420x60=25200

3.330hm/menit=1.980km/jam
hm→km=:10=330:10=33
menit→jam=x60=33x60=1980

4.245cm/detik=8.820m/jam
cm→m=:100=245:100=2,45
detik→jam=x3600=2,45x3600=8820

5.66.000dm/jam=11.000hm/menit
dm→hm=x10=66.000x10=660.000
jam→menit=:60=660.000:60=11000

6.7.440m/jam=124m/menit
jam→menit=:60
=7.440:60=124

7.12km/jam=333,33cm/detik atau 333 1/3 cm/detik
km→cm=x100000=12x100000=1200000
jam→detik=:3.600=1200000:3.600=333,33

8.50dm/detik=0,3km/menit
dm→km=:10000=50:10000=0,005
detik→menit=x60=0,005x60=0,3

9.810dam/menit=135.000mm/detik
dam→mm=x10000=810x10000=8100000
menit→detik=:60=8100000:60=135000

10.54m/detik=19.440dam/jam
m→dam=:10=54:10=5,4
detik→jam=x3600=5,4x3600=19440

Dikoreksi kalau ada yang salah :)
Semoga membantu :)
