Question

Carry out the unit conversions: a) 36km/h to m/s and m/min b) 2000m/min to m/s and km/h

Answer 1

Answer:

a) 36 km/hr

to convert km/hr to m/s,

  we know 1 km = 1000m and 1 hr = 3600s

   So, 1 km/1 hr = 1000s/3600s = 5/18

    So, 1 km/hr = 5/18 m/s

          36 km/hr = 36 x (5/18)

                          = 10 m/s

   to convert m/s to m/min,

     1m = 1m and 1min = 60s

      1m/1s = 1m/60s

       1m/s = 60m/min

 so, 10m/s = 600 m/min

b) 2000 m/min

 we now know,

    1 m/s = 60 m/min

    1 m/min = 1/60 m/s

    2000 m/min = 2000/60 m/s = 33.33 m/s

  we know,

      1 km/hr = 5/18 m/s

      1 m/s = 18/5 km/hr

      33.33 m/s = 119.988 km/hr

HOPE MY ANSWER HELPED!!

And you got a small idea of how to do such conversions

[It is very simple, trust me...   ;) ]
