tollong sekarang juga dikumpulin kaka kan baik

1) waktu = 3 menit
jarak = 2 km × 4 = 8 km
kec = jarak ÷ waktu
= 8 km ÷ 3 mnt
= 2 ⅔ km/mnt

2) jarak = 490 km
kec = 100 km/jam
waktu = jarak ÷ kec
= 490 km ÷ 100km/jam
= 4 9/10 jam

3) kec = 385 m/dtk
waktu = 8 jam = 8 × 3600 = 28.800 detik
jarak = kec × waktu
= 385 m/dtk × 28.800 dtk
= 11.088.000 m
= 11.088 km

4) jarak = 4,5 km
waktu = 15 menit = 15/60 = ¼ jam
kec = jarak ÷ waktu
= 4,5 km ÷ ¼ jam
= 4,5 × 4/1
= 18 km/jam

5) jarak = 30 m
kec = 3 m/jam
waktu = jarak ÷ kec
= 30 m ÷ 3 m /jam
= 10 jam
= 10 × 60
= 600 menit

6) jarak = 60 km
berangkat = 07.00
kec = 15 km/jam
waktu = jarak ÷ kec
= 60 km ÷ 15 km/jam
= 4 jam
tiba = 07.00 + 04.00
= 11.00

7) jarak = 180 km
waktu = 10.00 - 06.00 = 4 jam
kec = jarak ÷ waktu
= 180 km ÷ 4 jam
= 45 km/jam

8) waktu = 2½ jam
kec = 20 km/jam
jarak = waktu × kec
= 2½ jam × 20 km/jam
= 50 km

9) jarak = 150 km
kec = 120 km/jam
waktu = jarak ÷ kec
= 150 km ÷ 120 km/jam
= 1 ¼ jam
= 01.15
keluar = 09.15 + 01.15 = 10.30

10) kec = 60 km/jam
jarak = 150 km
waktu = jarak ÷ kec
= 150 km ÷ 60 km/jam
= 2½ jam
= 02.30
tiba = 15.45 + 02.30 = 18.15
