Penjelasan dengan langkah-langkah:
1. Pak Roni
jarak tempuh = 4800 dam
= 48.000 m
kecepatan = V = 80 m/detik
waktu tempuh =
[tex] = \frac{jarak}{kecepatan} \\ = \frac{48000}{80} \\ = 600 \: \: detik \\ = 10 \: \: menit[/tex]
2.
jarak = 108 meter
= 10.800 cm
waktu = 1,8 menit
= 1,8 × 60
= 108 detik
Kecepatan =
[tex] = \frac{jarak}{waktu} \\ = \frac{10800}{108} [/tex]
= 100 cm/detik
Jawab:
1. waktu = 10 menit
2. kecepatan = 100 cm/detik

1. waktu = jarak : kecepatan
= 4.800 dam : 80 m/detik
= 48.000 m : 80 m/detik
= 600 detik
= 10 menit
2. kecepatan = jarak : waktu
= 108 m : 1,8 menit
= 10.800 cm : 108 detik
