120 km/h = 120 * 1000m/3600s =33,3 m/s ≈ 33 m/s
154 km/h = 154 * 1000m/3600s =42,7 m/s ≈ 43 m/s
42 m/s = 42 * (1/1000)km/(1/3600)s =151,2 km/h ≈ 151 km/h
112 m/s = 112 * (1/1000)km/(1/3600)s =399,6 km/h ≈ 400 km/h
Odpowiedź:
120 km/h × 1000/3600 = 12000/3600 ≈ 3,33 m/s
154 km / h × 1000/3600 = 1540/36 = 42,7777778 m/s
