Answer 1

1) waktu = 3mnt = 3×60=180
jarak = 1.800 mtr
kec = jarak ÷ waktu
= 1.800 ÷ 180
= 10 mtr/dtk
2) jarak = 7,2 km = 7,2×1000
= 7200 mtr
waktu =1jam= 1× 3600=3600dtk
kec = 7200/3600
= 2 mtr/dtk
3) kec = 340mtr/dtk
waktu = 0,2mnt =0,2×60=12dtk
jarak = 12 × 340 = 4.080 mtr
4) vol = 300dm³
debit = 2dm³/dtk
waktu = 300dm³/2dm³/dtk
=150dtk ÷ 60
= 2,5 mnt
5) vol 2.000 ltr
waktu = 30dtk
debit = 2000ltr/30dtk
= 66,7 ltr/dtk
