Penjelasan dengan langkah-langkah:

Nomor 1 :

a. v = s/t = 90 km / 3 jam = 30 km/jam

b. s = v × t = 20 m/ menit × 15 menit = 300 m

c. t = s/v = 128 km : 32 km/jam = 4 jam

d. v = s/t = 150 km / 2,5 jam = 375 km/jam

e. s = v × t = 80 km/jam × 3,5 jam = 280 km

Nomor 2 :

a. 24 km/jam = (24 × 1000 m) / (1 × 60 menit) = 24000 m / 60 menit = 400 m/menit

b. 54 km/jam = (54 × 1000 m) / (1 × 3600 detik) = 54000 m / 3600 detik = 15 m/detik

c. 180 m/menit = 180 m / (1 × 60 detik) = 180 m / 60 detik = 3 m/detik

d. 5 m/detik = (5 ÷ 1000 km) / (1 ÷ 3600 jam) = (0,005 km × 3600) / jam = 18 km/jam

e. 24 m/menit = (24 ÷ 1000 km) / (1 ÷ 60 jam) = (0.024 km × 60) / jam = 1,44 km/jam

f. 30 km/jam = (30 × 1000 m) / (1 × 3600 detik) = 30000 m / 3600 detik = 8,33 m/detik
