It makes sense to include the possible expressions since there is more than one way of doing this.

For some reason I'm getting \(t = \frac{x}{25} - 6.5\)
Hero
  • Hero
Which is none of those

Chero, is there a typo?
anonymous
  • anonymous
let me check...
anonymous
  • anonymous
No typos on the possible answers.

\[Rate = \frac{Distance}{Time}\] \[Time*Rate = Time*\frac{Distance}{Time}\] \[Time*Rate = Distance\] \[\frac{Time*Rate}{Rate} = \frac{Distance}{Rate}\] \[Time = \frac{Distance}{Rate}\]
anonymous
  • anonymous
I copied and pasted the question.
anonymous
  • anonymous
Substitute Distance and Rate to get the Time.
Hero
  • Hero
Wired, do you have an actual explanation or are you going to continue to talk in general?
anonymous
  • anonymous
That IS the explanation. Replace Distance and Rate and you have the answer.

I see. I was focused too much on setting up the problem to solve for t
anonymous
  • anonymous
so is the answer b??
anonymous
  • anonymous
I am terrible at word problems....they give me headaches.
anonymous
  • anonymous
What is the Distance? What is the Rate for the trip home?
anonymous
  • anonymous
Since the total time: 12:30 - 8= 6.5 hrs -> Return time : total - leaving time = ....
anonymous
  • anonymous
x/25 should be the answer. I am not sure I just went ahead and submitted my answers.
anonymous
  • anonymous
That's the correct answer.
Hero

Yes, Chero, no one wanted to give you the answer though

I am too tired, taking a quick break!! I appreciate your help. I am sure I will be back in about 20 minutes!

@Chero Take a look at my explanation!

Chrorophyll, they wanted the expression for time
anonymous
  • anonymous
That what it is: Return time = total time - start time
anonymous
  • anonymous
Starting time = x
anonymous
  • anonymous
@Chlorophyll Starting time is NOT X. As per the original statement: X represents how far it is to the destination.
anonymous
  • anonymous
"If x represents how far it is to the destination"
anonymous
  • anonymous
Yes, I just stated that. X is DISTANCE, not TIME.
anonymous
  • anonymous
Oh, I misread it :")

@mahmit2012 Yes, you solved for X, but the question didn't want X. @Chero Please close the thread and award a medal if you deem so.
