Answer:
speed in m/s=0.01822 metre/s
Step-by-step explanation:
Conversation rate of mm to m is
1000 mm = 1 metre
820 mm= 820/1000
829 mm= 0.82 metres
Conversation rate of minutes to second
I minute = 60 seconds
0.75 minute = 60*0.75 seconds
0.75 minute= 45 seconds
speed in m/s= 0.82 metres/45 seconds
speed in m/s= 0.82/45
speed in m/s=0.01822 metre/s
