Answer:
45.2 is the constant of proportionality
Step-by-step explanation:
Direct proportionality says that:
[tex]y \propto x[/tex] then the equation is in the form of:
[tex]y=kx[/tex], 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:
[tex]d \propto t[/tex]
⇒[tex]d= kt[/tex]
On comparing with [1] we have;
k = 45.2
Therefore, the constant of proportionality is, 45,2
