Is this the correct way to figure this story problem out?
Story problem: Franco Drove 203 miles in 3.5 hours. At this rate, how long would it take him to drive another 29 miles to the next town?
Would I add 203 + 29 and then divide it to 3.5?

$\huge \text {rate=} \frac{\text{distance}}{\text{time}}$

anonymous · Answer

"how long" means time

$\huge \frac{203}{3.5}=\frac{29}{x}$

anonymous · Answer

awesome... ok.. let me figure it that way

anonymous · Answer

Direct proportion: the numerators are the distance (miles), and the denominators are the time (hours). :)

Now cross multiply and solve for x.

anonymous · Answer

goodness!  .. I think I see!  Ill try to put it together!

anonymous · Answer

Do you need help to cross multiply it?

anonymous · Answer

Multiply $203$ and $x$. Add an equal sign. Then multiply $3.5\text{ and}~ 2.9$.

anonymous · Answer

It would be: $\huge\text { 203x=29(3.5})$

anonymous · Answer

Still confused?

anonymous · Answer
