Answer 1

50 m/detik = (50:1000) km / (1:3600) jam = (0,05x3600) km/jam = 180 km/jam

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

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

50 mm/detik = (50:1000) m / (1:60) menit = (0,05 x 60) m/menit = 3 m/menit

2 cm/detik = (2:100000) km / (1:3600) jam = (0,00002 x 3600) km/jam = 0,072 km/jam
