Answer:

answer given below

Explanation:

To convert speed in km /h to m/s :

Use the fact 1 km =1000m

1h=60minutes =60×60 s

So,  1km/h     =      1000/(60*60) m/s

                     =      ( 1000/3600) m/s

                     =        10/36  m/s

                     =        0.2778 m/s

Multiply by this factor

So,

320 km/h= 320×(10/36) m/s=88.89 m/s

Similarly,

40 - 46 km/h = 11.111  -  12.778 m/s

56 km/h =15.5556   m/s

19km /h =   5.2778  m/s  

11km/h  =    3.0556  m/s

40km/h =    11.1111   m/s

0.27km/h = 0.075000 m/s

0.05 km/h =  0.013889m/s
