Homework Help: Simple units conversion (km/h -> m/s)

  1. Aug 29, 2008 #1
    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??

    [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.
