Which one is greater?

OPtion

1) 400 kilometer/ day
2) 6 meter/ second
3) 20 kilometer/ hour
4) 400 meter/ minute
5) 500000 meter/ day
6) 0.005 kilometer/ second
7) 0.6 kilometer/ minute
8) 23000 meter/ hour
9) 550 centimeter/ second
10) 40000 centimeter/ minute

Solution

20 kilometer/ hour = 20*1000/3600 = 200/36 = 5.555 m/s
400 meter/ minute = 400/60 = 40/6 = 6.666 m/s
500000 meter/ day = 500000/86400 = 5000/864 = 5.787 m/s
0.005 kilometer/ second = 0.005*1000 = 5 m/s
0.6 kilometer/ minute = 0.6*1000/60 = 10 m/s
400 kilometer/ day = 400*1000/86400 = 4000/864 = 4.63 m/s
23000 meter/ hour = 23000/3600 = 6.389 m/s
550 centimeter/ second = 550/100 = 5.5m/s
40000 centimeter/ minute = 40000/(100*60) = 40/6 = 6.666 m/s
