Penjelasan dengan langkah-langkah :

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
