Answer:
The constant of proportionality is 1.5 and the value of q is 9.
Step-by-step explanation:
Assume Hours as 'x' and Miles walked = 'y'
Constant of proportionality means the same value of
is maintained throughout.
So, note that
= 1.5
This means that
should also equal 1.5.

= 9.
Therefore, the value of 'q' is 9.
