Answer:

45.2 is the constant of proportionality

Explanation:

Direct proportionality says that:


y \propto x then the equation is in the form of:


y=kx, where k is the constant of proportionality

As per the statement:

The distance, d, measured in miles, that Hye drove is

d = 45.2t, .....[1]

where,

t is the time in hours.

By definition of direct proportionality:


d \propto t


d= kt

On comparing with [1] we have;

k = 45.2

Therefore, the constant of proportionality is, 45,2
