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

For some reason I'm getting \(t = \frac{x}{25}  6.5\)

\[Rate = \frac{Distance}{Time}\] \[Time*Rate = Time*\frac{Distance}{Time}\] \[Time*Rate = Distance\] \[\frac{Time*Rate}{Rate} = \frac{Distance}{Rate}\] \[Time = \frac{Distance}{Rate}\]

Wired, do you have an actual explanation or are you going to continue to talk in general?
 2 years ago

Wired Group TitleBest ResponseYou've already chosen the best response.2
That IS the explanation. Replace Distance and Rate and you have the answer.

x/25 should be the answer. I am not sure I just went ahead and submitted my answers.

That's the correct answer.

Chrorophyll, they wanted the expression for time

That what it is: Return time = total time  start time

Chlorophyll Group TitleBest ResponseYou've already chosen the best response.0
Starting time = x
 2 years ago

Wired Group TitleBest ResponseYou've already chosen the best response.2
@Chlorophyll Starting time is NOT X. As per the original statement: X represents how far it is to the destination.

"If x represents how far it is to the destination"

Wired Group TitleBest ResponseYou've already chosen the best response.2
Yes, I just stated that. X is DISTANCE, not TIME.

@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.
