Answer:
33.33 m/s (2 d.p.)
Step-by-step explanation:
Conversions
- 1 minute = 60 seconds
- 1 hour = 60 minutes = 3600 seconds
- 1 km = 1000 m
To convert kilometres into metres:
- Multiply the kilometres by 1000.
To convert hours into seconds.
- Multiply the hours by 3600.
[tex]\implies \sf km/h=\dfrac{km}{h}=\dfrac{1000}{3600}=\dfrac{1}{3.6}[/tex]
So to convert kilometres per hour into metres per second, simply divide the km/h by 3.6:
[tex]\implies \sf120\;km/h=\dfrac{120}{3.6}=\dfrac{100}{3}=33.33\; \sf m/s\;(2\;d.p.)[/tex]
