Answer 1

Verified answer

1) 18 m = 1800 cm
18m/detik = 1800cm/detik

2) 15 m = 0.015 km
1 detik = 1/3600 jam
0.015÷1/3600 = 0.015 × 3600 = 54 km/jam

Meter diubah ke cm
18 m = 1800 CM
jadi 18 m/detik= 1800 cm/detik

15 m/detik = 54 km/jam
1 jam =3600 detik,
Maka 15 x 3600 = 54000 m/jam
= 54 km/jam
