Question

Pomóżcie Przelicz: 15km/h na m/s 76km/h na m/s 12m/s na km/h 42m/s na km/h

Answer 1

15 km/h = 15 *1000m/3600s ≈ 4,17 m/s

 

76 km/h = 76 *1000m/3600s ≈ 21,11 m/s

 

12 m/s = 12 * 0,001km/(1/3600h) = 43,2 km/h

 

42 m/s = 42 * 0,001km/(1/3600h) = 151,2 km/h

Answer 2

15km/h = 15 * 1000m/3600s= 5* 10m/12s = 5* 5m/6s = 25m/6s=4 1/6 m/s

76km/h = 76 * 1000m/3600s=76* 10m/36s=76 * 5m/18s = 380m/18s=21 2/18 m/s =21                   1/9 m/s

12m/s = 12/1000 : 1/3600 km/h=12/1000 * 3600 km/h= 12/5 * 18 km/h = 216/5 km/h=               43 1/5 km/h 

42m/s = 42/1000 : 1/3600 km/h= 42/1000 * 3600 km/h= 21/5 * 36 km/h = 756/5 km/h            =151 1/5 km/h
