Penjelasan dengan langkah-langkah:

Rumus --> kecepatan (v) = jarak (s) : waktu tempuh (t)

1. t = 10 menit, s = 2000 m --> v = 2000/10 = 200 menit

2. s = 6000 m = 0,6 km ; t = 5 menit = 1/12 jam --> v = 0,6 : (1/12) = 0,6 x 12 = 7,2 km/jam

3. t = 15 menit = 1/4 jam --> v = 20 : (1/4) = 80 km/jam

4. t = 20 menit = 1/3 jam --> v = 40 : (1/3) = 120 km/jam

5. t = 6 menit = 1/10 jam --> v = 12 : (1/10) = 120 km/jam

6. t = 15 menit = 1/4 jam --> v = 12,5 : (1/4) = 50 km/jam

7. v antasena = 6000m/3600 s = 1,6667 m/s

   v bima = 20 m/s --> v bima > v antasena maka bus bima melaju lebih cepat.
