The ferry travels at a fixed rate or the same speed. The fraction of distance traveled by ferry in one hour is 7/18 or 0.389 of the distance between the ports.
Let x be the distance between two ports.
A ferry travels 1/6 of the distance x in 3/7 hours. Mathematically, it can be written as [tex]\dfrac{x}{6}[/tex] distance is traveled in 3/7 hours.
The ferry travels at the same rate.
So, the distance traveled in 1 hour will be,
[tex]\dfrac{x}{6}\times \dfrac{7}{3}=\dfrac{7x}{18}[/tex]
So, the distance traveled by ferry in one hour is [tex]\dfrac{7x}{18}[/tex].
Therefore, the fraction of distance traveled by ferry in one hour is 7/18 or 0.389 of the distance between the ports.
