Need help, please answer!

OpenStudy (anonymous):

Carlos and Maria drove a total of 258 miles in 5 hours. Carlos drove the first part of the trip and averaged 53 miles per hour. Maria drove the remainder of the trip and averaged 51 miles per hour. For approximately how many hours did Maria drive? Round your answer to the nearest tenth if necessary.

OpenStudy (anonymous):

ok so how exactly are we supposed to answer this if it doesn't even tell us how far Carlos drove?

OpenStudy (anonymous):

I have no idea, that's why I'm confused.

OpenStudy (the_fizicx99):

Carlos drove the first part of the trip and averaged 53 miles per hour

OpenStudy (anonymous):

yeah but he drove 53 mph thats not telling us how long or how far which means this is a Rhetorical question

OpenStudy (the_fizicx99):

Yeah idk.. >.> missing information ohhh 53 and 51 find a way both add up to 258 withing the 5 hour limit and approximate how many maria drove.

OpenStudy (anonymous):

I guess beats me

OpenStudy (anonymous):

Well, thanks for trying :P

OpenStudy (anonymous):

we can solve it with that info though right? @tHe_FiZiCx99

OpenStudy (the_fizicx99):

Lets try @shelbygt520 :3 duoo lulz Um 53*3 = 159 51*2 = 102 + 159 = 261mph Close

OpenStudy (anonymous):

yeah close umm try 53*2 and 51*3

OpenStudy (anonymous):

Damn thats 1 mile over

OpenStudy (the_fizicx99):

Were going to have to round, says round to the nearest tenth so I think we're going to need to use a decimal? 53*2 = 106 51*3 = 153 + 106 = 259

OpenStudy (the_fizicx99):

One off, 51*3.5 = 178.5 53*1.5 = 79.5 79.5 + 178.5 = 258mph Rounded..?

OpenStudy (the_fizicx99):

Idk what that would be rounded

OpenStudy (anonymous):

ehh yeah thats right but now I'm all confuthled and yeah.... -_-

OpenStudy (the_fizicx99):

?How? o.o

OpenStudy (the_fizicx99):

It's simple lol ._.

OpenStudy (anonymous):

wait if 153 plus 106 equals 259 then we can round it out to Maria driving 3hours

OpenStudy (anonymous):

because if we were to put it down to the exact time we'd get into the milliseconds

OpenStudy (the_fizicx99):

Yes, but to the tenth place?

OpenStudy (anonymous):

yeah @MustHaveAnswers do you have an option to the tenths place?

OpenStudy (the_fizicx99):

3.50 is the same as 3.5 so it is in the tenth place|dw:1387571246755:dw|
