Answer:

a) constant of proportionality = 196

b) constant of proportionality represents the speed of the airplane in miles per hour

Step-by-step explanation:

The proportionality relationship is

y ∝ x where y = distance flown in miles and x is time in hours

This can be modeled as an equation
y = k. x  where k is the constant of proportionality

The equation given is y = 195x so 195 is the constant of proportionality , it is basically the speed of the airplane in mph
