Answer:
The constant of proportionality in terms of d to t is 4.5.
Step-by-step explanation:
Since,
\(Distance = Speed\times Time\)
So, we can write,
Distance is directly proportional to time if speed is constant.
Here d represents distance and t represents time,
\(\implies d\propto t\)
\(\implies d=kt\)
Where k is the constant of proportionality,
We have given,
d = 4.5t
By comparing k = 4.5,
Hence, the constant of proportionality in terms of d to t is 4.5.
