Answer:
Ferry rate = [tex]\frac{7}{18}[/tex] miles/hour
Solution:
Ferry travelled [tex]\frac{1}{6}[/tex] miles of distance between two ports in [tex]\frac{3}{7}[/tex] hours
Rate of Ferry is equal to distance travelled over time taken.
Rate of ferry = [tex]\frac{\frac{1}{6}}{\frac{3}{7}}[/tex]
Now we calculate it.
Rate of ferry =[tex]\frac{1}{6}\div \frac{3}{7}[/tex] miles/hour
Rate of ferry = [tex]\frac{7}{18}[/tex] miles/hour
