Unit 1=10 m/s.
Unit 2=1 km/min=60 km/hr = 60*5/18 m/s=16 2/3 m/s.
Unit 3=18 km/h=18*5/18=5 m/s.
Clearly, 5 m/s < 10 m/s < 16 2/3 m/s.
So,
18 km/h < 10 m/s < 1 km/min.
Unit 2=1 km/min=60 km/hr = 60*5/18 m/s=16 2/3 m/s.
Unit 3=18 km/h=18*5/18=5 m/s.
Clearly, 5 m/s < 10 m/s < 16 2/3 m/s.
So,
18 km/h < 10 m/s < 1 km/min.
