Answer:
[tex]s=390\ km[/tex]
The formula is [tex]s=6v[/tex]
Step-by-step explanation:
Let
s -----> the distance in kilometers
t ----> the time in hours
v ----> the speed in km/h
we know that
The speed is the ratio of the distance by the time
[tex]v=\frac{s}{t}[/tex]
Solve for s
[tex]s=vt[/tex]
we have
[tex]t=6\ h[/tex]
therefore
The formula is [tex]s=6v[/tex]
For [tex]v=65\ km/h[/tex]
substitute in the formula
[tex]s=6(65)[/tex]
[tex]s=390\ km[/tex]
