Answer:
The equation for the relationship is 
.
Step-by-step explanation:
Given that point 
is part of a direct relationship. That is:
(1)
Where 
is the proportionality constant.
If we know that 
and 
, then the proportionality constant is:
Lastly, the equation for the relationship is .
1.15(300).
Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.
1.15(300)=345 miles per hour
After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).
