Hi!!

don't you hate word problems?

we can do it though for sure

ok, thanks!

we are gong to use distance equals rate time time time, or time is distance divide by rate

we don't know what the distance is, so lets call it D

time going it
\[\frac{D}{8}\]right?

yes..

and time returning is?

D/12

right
so total time is
\[\frac{D}{8}+\frac{D}{12}\] which your are told is 1

solve
\[\frac{D}{8}+\frac{D}{12}=1\] for \(D\) and you are done

do you know how to do that?

oh btw they ask for the round trip, so once you find D the answer is actually 2D

Do we need to find a common denominator first?

I did it the first way because it was easier for me, I got D = 4.8

i didn't do it, let me check

And then 2*4.8 = 9.6.
Thank you so much for helping!

if you multiply by 24 you get
\[3
d+2
d=24\\
5D=24\\
D=4.8\] yeah you are righ t
