a) To convert m/s to km/h, we multiply by 3.6.
3.6 m/s = 3.6 * 3.6 km/h = 12.96 km/h

b) To convert km/h to m/s, we divide by 3.6.
7.2 km/h = 7.2 / 3.6 m/s = 2 m/s

c) To convert m/s to km/h, we multiply by 3.6.
10 m/s = 10 * 3.6 km/h = 36 km/h

d) To convert m/s to km/phút, we multiply by 60.
10 m/s = 10 * 60 km/phút = 600 km/phút

e) To convert km/h to cm/s, we multiply by 100.
5 km/h = 5 * 100 cm/s = 500 cm/s
