Best ResponseYou've already chosen the best response.0I don't know how to solve big square roots really. But I need this now :( @Astrophysics

Best ResponseYou've already chosen the best response.0\[2\sqrt{525}\] maybe that's easier, just keep simplifying that

Best ResponseYou've already chosen the best response.0Okay I got 10 times sqrt21 @Astrophysics

Best ResponseYou've already chosen the best response.0Okay 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

Best ResponseYou've already chosen the best response.0So S is your speed and L is your length this is exactly the same as your problem above

Best ResponseYou've already chosen the best response.0I guess you don't have to convert any units either ft into miles or what ever does look like it

Best ResponseYou've already chosen the best response.0so that's the answer 10 times sqrt ?

Best ResponseYou've already chosen the best response.0Sqrt21 ? So there is no rounding to the nearest mph
