Question

The jones family plans a 300 mile trip. Let y=time traveled (in hours) and x=average speed (in miles per hour). Write the equation for the rectangular hyperbola that expresses the relationship between time traveled (y) and average speed (x).
Y=300X
XY=300
300Y=X

Answer 1

The basic formula is XY = 300.  Since we know the distance formula would be d = rate * time. 

Answer 2

Answer:

Option 2nd is correct

$xy = 300$

Step-by-step explanation:

Using formula:

$\text{Distance} = \text{Speed} \cdot \text{Time}$

Here, y represents the time traveled (in hours) and x represents the average speed (in miles per hour).  

Given the statement:

The Jones family plans a 300 mile trip

⇒ $\text{Distance} = 300$ miles

Using formula we get;

$300 x \cdot y$

⇒$xy = 300$

therefore, the equation for the rectangular hyperbola that expresses the relationship between time traveled (y) and average speed (x) is :

$xy = 300$
