Question

cum transformi 30m pe secunda in m pe ora

Answer 1

30 m/s =30•3600/1000 km/h=30•3,6 km/h=108 km/h

Answer 2

In metri pe ora:

$30\dfrac{m}{s}=30\dfrac{m}{\dfrac{1}{60\cdot 60}h}=30\dfrac{3600m}{h}=108\cdot 10^3\dfrac{m}{h}$

In kilometri pe ora:

$30\dfrac{m}{s}=30\dfrac{\dfrac{1}{1000}km}{\dfrac{1}{60\cdot 60}h}=30\dfrac{3,6km}{h}=108\dfrac{km}{h}$
