Answer:

Step-by-step explanation:
Let the distance be
and the time be
.
It was given that the distance,
, varies directly as the square of the time
, we write the proportional relation,
.
, where
is the constant of variation.
It was also given that,
, when
.




Now the equation of variation becomes;

When,
