3.15m/detik= km/jam
4.0.5km/menit= km/jam
5.40cm/detik= m/menit
6.50mm/detik= m/menit
7.2cm/detik= km/jam
kak tolong ngerjakannya pakai cara

Answer 1

1. 72000/3600 = 20. 2. 2400 / 60 = 40.

Answer 2

1)
72 km/jam
= (72x1.000) m/3.600 detik
= 72.000 : 3.600 m/detik
= 20 m/detik

2)
2,4 km/jam
= (2,4x1.000) m/60 menit
= 2.400 : 60 m/detik
= 40 m/detik

3)
15 m/detik
= (15:1.000) km/(1/3.600) jam
= 0,015 x 3.600 km/jam
= 54 km/jam

4)
0,5 km/menit
= 0,5 km/(1/60) jam
= 0,5 x 60 km/jam
= 30 km/jam

5)
40 cm/detik
= (40:100) m/(1/60) menit
= 0,4 x 60 m/menit
= 24 m/menit

6)
50 mm/detik
= (50:1.000) m/(1/60) menit
= 0,05 x 60 m/menit
= 3 m/menit

7)
2 cm/detik
= (2:100.000) km/(1/3.600) jam
= 0,00002 x 3.600 km/jam
= 0,072 km/jam
