MEDAL AND FAN!!!!! PLEASE HELP!!!!!

OpenStudy (anonymous):

what do you need help with

OpenStudy (anonymous):

It's up above

OpenStudy (anonymous):

cant see the whole thing

OpenStudy (anonymous):

ok hold on

OpenStudy (anonymous):

Ashley paddle from one shore of a lake six miles wide at 8 mph, and Claire paddles from the opposite shore at 10 mph

OpenStudy (anonymous):

How long will the travel before they meet?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

solving.....

OpenStudy (anonymous):

Can you give me an equation or something to use to figure it out

OpenStudy (anonymous):

distance = rate x time or d = r*t

OpenStudy (anonymous):

So is the equation 6=8x?

OpenStudy (anonymous):

Can you explain it to me? Or give me the equation with the numbers in it please?

OpenStudy (anonymous):

sorry im trying to figure it out myself havent done this stuff in a long time

OpenStudy (anonymous):

It's okay :) Take your time

563blackghost (563blackghost):

you still need help?

OpenStudy (anonymous):

yes please

563blackghost (563blackghost):

ok let me first finish off with someone else first and then Ill come here ^^

OpenStudy (anonymous):

Ok thx

563blackghost (563blackghost):

Well we will use \(\Large{D=r\times t}\) where D is \(\large{6}\)....we know the speeds that they both are traveling which is \(\large{8mph}\) and \(\large{10mph}\) but we dont know the time between them both so our equation is... \(\Large{8T+10T=6miles}\) in which we add like terms... \(\Large{18T=6miles}\) we now would divide by 18 on both sides...

OpenStudy (anonymous):

So divide 6 by 18?

563blackghost (563blackghost):

Yup^^ are there answer choices for this?

OpenStudy (anonymous):

So tbh this isn't the actual equation..... Sorry... I wanted to change it up so that I could solve the same type of problem twice to make sure I understood it. In the real equation the lake is miles wide and the speed are 4 and 5 mph.

OpenStudy (anonymous):

but yes there are answer choices to it

563blackghost (563blackghost):

may i see them?

OpenStudy (anonymous):

A. 1 hour, 24 minutes B. 27minutes C. 3 hours D. 20 minutes

OpenStudy (anonymous):

So I assuming the the equation is 9T=3 miles

OpenStudy (anonymous):

So the answer is C right? 3 hours

563blackghost (563blackghost):

Not really your equation is correct but the quotient is incorrect you would divide 3 by 9...\(\Large{\frac{3}{9}}\)...then you would multiply the simplified fraction by 60 to get how many minutes it took.....

OpenStudy (anonymous):

So then it's 20 minutes?

563blackghost (563blackghost):

Yup ^^

OpenStudy (anonymous):

thanks

\(\Huge\cal\rlap{\color{red}{No~Problem!:)}}{\color{blue}{\;No~Problem!:)}}\) \(\Huge\cal\rlap{\color{orange}{You~did~A~Great~Job!:)}}{\color{blue}{\;You~did~A~Great~Job!:)}}\)

OpenStudy (anonymous):

haha, thanks for showing me the choices:/

OpenStudy (anonymous):

sorry :(
