Help in solving this

  1. Feb 19, 2004 #1
    I havent had any math in like 4 years and I'm very rusty. Could someone please show me a "step by step" how to solve an equation like this...

    (30m/s - 10m/s)/2.0s = 10m/s^2

    I forgot how to get to the answer.This example came from my book. Can someone please explain how the answer became 10m/s^2 ?

    I got lost with the metere/second square

    Please help

    Thanks in advance.

    [tex]\frac{(30m/s - 10m/s)}{2.0s} = [/tex]

    [tex]\frac{(20 m/s) }{ 2s} = [/tex]

    [tex]\frac{20}{2}\frac{m/s}{s} = [/tex]

    [tex]10 \frac{m}{s}\frac{1}{s}=[/tex]


    Remember: [tex]\frac{a}{b}/c=\frac{a}{b*c}[/tex]
