Two planes, which are 3600 miles part, fly toward each other. Their speeds differ by 50 mph. if they pass each other in 4 hours, what is the speed of each?  
use the x variable to set up an equation to solve the given problem

anonymous · Answer

guess we have to use distance equals rate times time

anonymous · Answer

put one speed as say $x$ and the faster speed is then $x+50$ 
you know their combined speed is therefore $x+x+50=2x+50$

anonymous · Answer

yeah im struggling with this

anonymous · Answer

then since $D=RT$ we know $T=\frac{D}{R}$ and you know $T=4$, also $D=3600$ the only thing you don't know is $x$
solve 
$$\frac{3600}{2x+50}=4$$ for $x$

how would I find the speed of each? @satellite73 do I just sole for x?
