In part a), you mean $y = \dfrac{75x}{2x - 75} $, right?

yes!!! help!!! =(

mathstudent55 · Answer

Ok. You need to know a few things about the average.
An average speed is the distance divided by the time.

mathstudent55 · Answer

The average speed of the round trip was 75 mph.
What was the total distance traveled in the round trip?

anonymous · Answer

300 miles

so average speed would be 300/75=4  ??

mathstudent55 · Answer

No.
Each trip between cities is 300 miles.
The total round trip is going and coming back.
How many miles is the total round trip?
