An airplane travel at a constant speed of 575 miles per hour.write and equation that can be used to determine the number of mile

Oxana [17]

Answer:

$m = 575h$

Step-by-step explanation:

Given

$Rate = 575 miles/hour$

Required

Determine the equation for the model

Represent the number of hours with h and the miles with m.

Using distance formula:

$Distance = Speed * Time$

In this case, it is:

$Miles = Rate * Hour$

So, we have:

$m = 575 * h$

$m = 575h$

Identifying a constant of variation question<br><br> R= ?

jek_recluse [69]

Pressure and Volume are inversely related as:

$P= \frac{R}{V}$

We can also write it as:

$PV=R$

R is the constant of proportionality. Using the first row of given table, we can write:

$2(4.155)=R \\ \\ 
R=8.31$

Thus, the value of R, the universal gas constant is 8.31
