Question

1. 54 k/h= .... ? m/s 2. 50m/s =.... ? km/h 3. 20 dm/s= ...? m/mm

Answer 1

54 km/h = 54 * 1000 m/3600 s = 54000 m/3600 s = 15 m/s

50 m/s = 50 * 1/1000 m/1/3600 h = 50/1000 m * 3600/1 h = 180 km/h

20 dm/s = 2 m/s

20 dm/s = 2m/1/60 min = 120 m/min

 

1 km = 1000 m

1 m = 1/1000 km

1 h = 3600 s

1 s = 1/3600 h

1 m = 10 dm

1 s = 1/60 min
