Karena 1 m = (1/1000) km dan 1 s = (1/3600) jam, maka
1 m/s = (1/1000) km / (1/3600) jam = 3,6 km/jam
10 m/s = 10 x 3,6 km/jam = 36 km/jam
20 m/s =20 x 3,6 km/jam = 72 km/jam
30 m/s = 30 x 3,6 km/jam = 108 km/jam
100 m/s = 100 x 3,6 km/jam = 360 km/jam
jadi 60 m/s = 60 x 3,6 km/jam = 216 km/ jam
sudah mengerti?
