change into si unit. 18000km/m,3600cm/m,5400m/h,5400cm/s

Answer 1

Hi,

Here is your answer

18000 km/min = 18000000/60 m/s
                         = 300000 m/s

3600 cm/min = 36/60 m/s
                        = 0.6 m/s

5400 m/h = 5400/3600 m/s
                  = 1.5 m/s

5400 cm/s = 54 m/s

Hope this helps you.
