    \[2\sqrt{5(105)}?\]

    I don't know how to solve big square roots really. But I need this now :( @Astrophysics

    \[2\sqrt{525}\] maybe that's easier, just keep simplifying that

    Okay I got 10 times sqrt21 @Astrophysics

    Okay well I'm solving this problem LAW ENFORCEMENT:  A police accident investigator can use the formula S25L to estimate the speed s of a car in miles per hour based on the length l in feet of the skid marks it left.  How fast was a car traveling that left skid marks 105 feet long? And I have to round the answer to the nearest mph @ Astrophysics

    So S is your speed and L is your length this is exactly the same as your problem above

    plug L = 105

    I guess you don't have to convert any units either ft into miles or what ever does look like it

    so that's the answer 10 times sqrt ?

    Sqrt21 ? So there is no rounding to the nearest mph

    Then put it in decimals if it's asking in that
