    Help with calculating a download speed

    Hi everybody

    I'm trying to calculate a download speed for a homework assignment and I'm struggling a bit. I'm not asking for anybody to answer the question for me, I would just like somebody to explain what I need to do in order to work it out. The question I am struggling with is:

    If you have an internet connection with a download speed of 4135 kilobytes per second, how long would it take to download a 124 kilobyte file?

    I know the answer is obviously less than one second, but I am unsure about how to accurately calculate how many milliseconds it would take. Any help would be appreciated

    Thanks

    t = \frac{124 \, kb}{4135 \, kb/s} = 0.029987... \, s \, \approx 30 \, ms

    Using the formula total = rate \times time, or time = total \div rate, you see how skeeter's method works.
