In this question, the relations between velocity, distance and time are explored to first express the dependence of s on v, given the data in the exercise, and then to find the value of v for which s = 363.
Relation between velocity, distance, and time:
We have that velocity is distance divided by time, that is:

In which v is the velocity, d is the distance, and t is the time.
A car traveled s kilometers in 6 hours with a speed of v kilometers per hour.
This means that 
Express the dependence of s on v.
Taking the above values of d and t, and the formula, we have that:



Thus, the dependence of s on v can be expressed as: 
Using the formula, find: v for s=363
We have that:

And thus

Considering
:

Thus, for s = 363, v = 60.5.
