oggfile said:So the problem is:
Convert 35 km/h to in m/s.
I know that:
- 1 km = 10^3 m
- 1 h = 60 s
So I do:
35 km/h (10^3 m/1 km) (1 h/60 s) = 583 m/s
But the answer is 9.7 -- What??
stewartcs said:[tex]\frac{35km}{h} \cdot \frac{1000m}{1km} \cdot \frac{1h}{3600s}[/tex]
There are more seconds in an hour than 60!
Hope this helps.
