A) 2km/h = 2 1000/3600 = 5/9 m/s
b) 10 km/h = 10 1000/3600 = 2 7/9 m/s
c) 12km/h = 12 1000/3600 = 3 1/3 m/s
d) 130 km/h = 130 1000/3600 = 36,1 m/s
e) 1200 km/h = 1200 1000/3600 = 333,3 m/s

A)2 km/h
2*1000/3600m/s=20/36=0,5m/s

b) 10km/h
10*1000/3600m/s=100/36=2,7m/s

c)12 km/h
12*1000/3600m/s=120/36=3,3m/s

d)130km/h
130*1000/3600m/s=1300/36=36,1m/s

e)1200 km/h
1200*1000/3600m/s=12000/36=333,3m/s
