An alien rocketship is traveling at a speed of 34 feet per second. At this speed, how many miles will it travel in 1 hour? Round to the nearest thousandth.
Heres a hint say you have a scale of measurement a,b,c,d,e,f,g,h the scale between each level is 2 also not related to y so a = 2 , b = 4 , c = 6 , d = 8 , e = 10 , f = 12 , g = 14 , h = 14 2a = b X is y/a you want to see what it is for y/h Xy/a or X travels at y/a Xya ( X y / a ) ( 2 a / b ) = ( 2Xy / b ) note you have converted a units into b units ( 2Xy/b ) ( 2b/c) = ( 4xy/c) conversion of b to c now b to c = 4xy/c thats process of converting units of measure we could have other unit of measure say its j, k ,L, m, y each unit is a factor 10 10,100 ,1000, 10,000 ,100,000 convert to L ( 4xy/c ) ( 10m / y ) = 40 xm / c 40 xm / c ( 10L / m ) = 400 xL/ c I hope I did that correctly if not someone say some thing !!!!! back to original problem An alien rocketship is traveling at a speed of 34 feet per second. At this speed, how many miles will it travel in 1 hour? Round to the nearest thousandth. 34 ft / sec . . 




here is video for converting units
more elegant than my explanation http://www.khanacademy.org/video/con...lopmental+Math 




ok i'll [play 34 ft./sec x 60 = ft.per min.(2040) x 60 = ft/hr.(122400) /ft. per mile (5280) = 23.182 mph
not sure if this is what ur looking for... prolly not 




not sure havent done problem yet
however at first glance your concepts seem sound 




I guess this is a math exercise for Americans
As the rest of the world deals with Meters, Kilometers........LOL (just kidding) 




@ trap ok easy enough... convert to kilometers/hr.
i'll give you the answer (basically) .305 (rounded) meters per ft. 




the real lesson is knowing how to convert any type of units
once you grasp concept then any units can be manipulated to yield desired result I'm also studying probabilities not ready to start those yet but maybe I should 




On another note less than 4 months and I have completed over 50 % of Khan academies math tree
That's 140 lessons of a possible 276 They do keep adding lessons though. :P You would have to say that I have completed the easiest 50 % though since I started at the most basic , such as 1+1 = 2 type modules . Still i have yet to hit any permanent roadblocks . Out of 140 lessons only 10 or so gave me major difficulty , and only one really was super hard . If i crack all the lessons I will be pissed if they don't add higher levels . Then again they may have levels that I will fail to understand. That's what makes it interesting , will I survive the entire math tree ? Or will I reach a point where I cant understand it !!!! To me thats kind of exciting . Heres my graph you can see there were huge chunks of time where I didnt do anything It a great site to improve your math skills

34 ft / sec 34 ft / sec ( 1 mile /5280 ft ) = 0.006439 miles/sec 0.006439 miles/sec ( 60 seconds / 1 minute) = 0.38636 miles / minute 0.38636 miles / minute ( 60 minutes / hour ) = 23.182 miles / hour 23.182 miles / hour well mtnestegg we seem to agree so either we both screwed up or that is correct . . 




Was the spaceship travelling in a straight line? If it was in orbit it might have got back to where it started  and of course the universe is still expanding, and it is curved, should these factors be tajen into account?
These are just a few of the excuses I used today for not bothering with maths. I'm just happy I can add up  and do basic 'statistics'. Still  one of the more interesting and challenging threads. I'm more a crossword man myself, but I could get hooked on these. Just not good at maths. But  if you know maths you should know this one What do you call a one sided lapdancing bar....?

I think I stretched it out so I would not make a mistake
should I do a series on probabilities ????? If people followed along poker math would make a lot of sense . Probabilities are not in my lesson plans ( which I create myself :P ) I could do them tough 




ok nobody wants to do this i guess so i will for ya. 34 ft x .305 = 10.37 meters /second 10.37 x 60= 622.2 meters/ min. 622.2 x 60= 37332 meters/ hr. 37332/ 1000 (1000 meters in a km.) = 37.332 km/hr. simple pimple
"DISCLAIMER" as i rounded meters/ foot this is not the exact answer but op did say to round to thousandths. (actually .3048 meters/ft) so i did at the start which is not really the way to do it but made life easier from the get go which is how i try to approach life in general (you should actually round your answer, not before) as Americans we need to have some of these equivalents memorized so when traveling we have some clue at least. or that's my belief anyhoo 




sure.
